Blum TANDEM plus BLUMOTION Drawer Slide Kit – Full Extension with BLUMOTION Soft Close

Open a drawer equipped with Blum Tandem Plus Blumotion slides, and by the time it's closed, you'll be won over.
Item #
90% of 100

Incredibly smooth full-extension action combined with a self closing mechanism that engages 2" before the drawer is closed, and ever so gently eases it back into the cabinet, make these slides truly top-of-the-line. Add to that the fact that the slides are totally concealed - no clunky metal to detract from the beauty of your wooden drawers - and you have a recipe for a classic. This newest generation of Tandem Plus Blumotion features mounting holes on the bottom of the slide housing (except 12" slide) so you can mount the slides directly to a horizontal surface.


  • Tool-free tilt adjustment
  • Tool-free rear side-to-side adjustment
  • Easy four-dimensional adjustments
  • Elongated holes for depth adjustment
  • Full extension concealed runners with BLUMOTION soft close
  • Concealed roller carriage with permanently lubricated synthetic rollers
  • TANDEM runners are designed for the American 3" increment cabinet depth system. This feature permits overlay or inset applications to use the same runner. Full length runners make installation in panel or face frame cabinets possible.
  • For faster, more flexible adjustment of your drawer fronts, try the optional Adjustable Drawer Locking Device (#46209), which replaces the standard locking device that come with the slides.

Excellent slide with a poorly designed piece
Excellent slide. My customer was very pleased. But the provide angle to mount to the rear of the cabinet does not fit. Poor design on that piece.

The best undermount, soft close slides around. Thanks to the install specs for these I have the ability to build the drawers before the cabinet boxes. Saves me precious space and gets the job out faster.

These worked very well
I had one trouble. This was for a long drawer when I realized that I added a 1/2 inch plywood to the back.
At this point, it all went in flawlessly.
Thank you

The depth of my cabinet is 24" and the total length of the drawer is 22", what size of Blum tandem should I use ?
Rodolfo C on Sep 20, 2015
I have 21 inch drawers but the the drawer box is 3/4 inch thick. Will this drawer glides work with this drawer?
Ctawoodart on Jan 13, 2016
BEST ANSWER: No. As noted in the description, they can handle a maximum drawer side thickness of ⅝". Blum does make an undercount glide for ¾" material - they are the F & A series. (I believe these are the H series.) I don't know if Rockler carries the other series or not as they don't specifically list the part numbers.

If you need to use ¾" material, your options are to either trim/rabbit the bottom of the drawer sides to ⅝" or buy the glides designed for ¾" material.
If I buy 21" slides, what is my depth of cabinet to being built?
Brian B on Mar 26, 2016
BEST ANSWER: Typically, you would use a 21" slide with a cabinet that is 24" deep, which is a standard cabinet depth (typically kitchen boxes). Over the years, Blum (German company) has engineered their entire line of slides to conform to the cabinet construction standards in North America.
Can these slides be used if I am looking to only mount the cabinet member to the bottom of cabinet, and not the side of the cabinet wall?
Josh A on Dec 17, 2015
BEST ANSWER: Yes, these slides can be mounted to the sides or bottom of the cabinet enclosure. They also can be mounted to the face frame and back of the cabinet with the provided hanger.
how to adjustment of the soft close to close softer?
Julie H on Feb 10, 2016
BEST ANSWER: Use the adjustable locks for these slides - then you can adjust the drawer left or right on each side for a smoother close
Can these drawer slides be used outside in a kitchen island?

BEST ANSWER: I really do not know. If by "outside" you mean the slides could get wet with rain, I would say no. These things appear to be intended for dry service. BUT, they seem to operate well year in and year out in kitchens and bathrooms where relative humidity is sometimes high. I suggest you contact the manufacturer or a knowledgible vendor for better info.
do these come with the rear mount brackets?
A shopper on Jul 15, 2015
BEST ANSWER: Yes they do. It mounts to the back of the cabinet wall. You may have to put a spacer if the cabinet is deeper than the bracket allows.
Is there any side adjustment on these drawer slides, to allow for small variations in width of cabinet? If so, how much?
Nick W on Jul 21, 2016
BEST ANSWER: The short answer in No. However if your drawer is less in width than the directions require you could add a filler strip along one side to make up the difference. If you are concerned that the inside of the cabinet isn't exactly square to the drawer you could add a shim wherever you need to. Doing so might require some trial and error. Of the six drawers that I've made and installed I'd be hard pressed to say that my measurements were exactly right-on. There's probably a little slop built in to the scheduled measurements within the directions. Otherwise I'd still be fussing with mine. All in all my feelings for these drawer slides is that after you get through the first one it gets a lot easier.
We have to replace with side wall mounted you have an option for that?
BonBon on Dec 19, 2015
BEST ANSWER: Just put the screws into the side . There are holes for that.
I want to create a 12" deep waste cabinet but all the "rev" and other products are for typical 21" deep base cabinets. In my case the "base" cabinet is actually an "upper" cabinet that is only 12" deep x 15" wide x 30" high. I'd love to be able to put a pull out waste bin in the cabinet for all of the spam snail mail I receive. Any suggestions?

BEST ANSWER: Think drawer, or possibly drawers, and use 12 inch full extension or over extension slides.
In all the literature, and videos, the drawer faces are outside the cabinet case. Can these slides be installed so that they can be used with flush, or inset drawer faces?
Jaimi on Mar 24, 2017
BEST ANSWER: Yes. I used these slides with flush mount drawers
Are the rear mounting brackets absolutely necessary? My face frames are flush with the inside of the cabinet, and I'd like to just use the holes on the side rails for mounting.
HeavyD on Sep 6, 2016
BEST ANSWER: No, you do not need them. The slides need to be flush with the opening. The rear brackets are for when the face frame is NOT flush with the side of the cabinet. If your face frame was NOT flush and you did not have these brackets, you would have to make a shim to fill the space between the cabinet wall and face frame edge.
My drawer is a total of 9", will a 9" slide work?
Chas58 on Aug 15, 2017
BEST ANSWER: what ever size your box of the drawer is (not including the face of the drawer which is the part you put your drawer pul to open it).For example, if your box you build for your drawer is 12 inches your slides will be 12 inch slides,If your box is 18 inches, you will use 18 inch slide,etc So yes,a 9 inch slide will work for a 9 inch draw box.Do not include the thickness of the face you put on the front of your box.For example if the face you put on the front of the box is 5/8 inch thick your total length will be 9 and 5/8.Your slide will be just the 9 inches.Will be easy to remember that because you wont find a 9 and 5/8 inch slide
Can you use these on a 3/4" drawer instead of 5/8th?
Kelli Q on Mar 25, 2017
BEST ANSWER: I am guessing you are referring to the recess on the bottom of the drawer. Short answer is no. Long answer is you would need to shim them out or take the boxes apart and re-cut the dado for the bottom. Shimming out by covering the whole bottom with 1/8 inch plywood may be the answer.
The instructions state: "NOTE: Use of the T65.1600 template is essential for accurate location and angle of pre-bored
locking device holes and accurate boring for rear hook holes." No T65.1600 template was provided with the drawer slides. No mention of this template in any of the reviews or Q&A. Is the T65.1600 template necessary? If so, where can I buy one? I purchased my drawer slides at Rockler but can't find the template there.
William G on Dec 6, 2017
BEST ANSWER: I installed the slides on a 5-drw chest. They are really nice but EXTREMELY difficult to install. I did not have the template. It took lots of patience and modeling to get it right. I won't use them again, but if I did I'm sure it would be much easier. I was trying to match other furniture that had them. I was trying to maximize the drawer space. If I had used the recommended dimensions, they probably would have gone in with no trouble, but I would have given up valuable drawer space.
What is Blum's model number for these slides? I saw someone claim they are 563H but Blum doesn't make the 563 in a "H".
Eric R on Dec 1, 2017
BEST ANSWER: I looked on the Blum website and found a chart that provides suggestions for various sizes of drawers. This email vehicle does not allow me to provide that detail in this response, however the 563H is the Tandem drawer slides Full extension with Blumotion for drawers with a maximum drawer thickness of 5/8" upto 21" deep.
The brochure (Tandem plus Blumotion) that the manufacturer provides gives more detail along with the planning guides.

The rockler website only provides this type of device although it isn't very clear other that the title of the device.
Good luck
is there something that prevents the drawer from sliding out on it's own?
navysniper7 on May 1, 2019
BEST ANSWER: Unless I am mis-understanding the question, the drawers are not meant to slide out on their own: they must be manually pulled out like any traditional drawer. The beauty of these drawer glides is when you CLOSE the drawer, not OPEN the drawer. When you push on the drawer to close it, the 'soft close' mechanism will catch the drawer and gently bring it to a closed resting position. I hope that help.
Do the 12 inch slides fully extend drawer out of face frame?
A shopper on Apr 10, 2015
BEST ANSWER: Yes, they come out flush with the face frame, however, if the drawer is immediately under the counter, the counter overhang will slightly interfere.
I have 20 inch OD deep drawers, will 21" Tandem Blumotion Drawer Slides
Item #: 44034 work on these drawers cabinet ID is 22 inches?
John R on Apr 13, 2017
BEST ANSWER: I've installed dozens of these & very satisfied w/ performance. The 21" TBDS length should fit nicely in your 22" deep cabinets. However, your drawer depth is limited to 18" so the back, fixed bayonet slide mount and the front removable clip set will fit witin the overall slide framework and the underneath of your finished drawer. Can you easily shorten the 20" drawer box to 18"? For the undermount slide mechanism to be completely invisible when the drawer is open, yoru drawer bottom needs to have a minimum space of 1/2" between bottom of drawer side and the drawer bottom. Installation instruction sheet that should come with the slides has dimensions and a drawing showing clearances & critical dimensions.
The depth of my cabinet minus the 3/4 face is 16 inches. Do I buy the 12 inch or the 15 inch?
charles M on Nov 6, 2016
BEST ANSWER: My guess is the 15" slides. You'll probably have to install a floater to give the slide a place to be anchored to. I think that the clips intended to support the rear of the slides are too short to account for the 1¾" extra space.

In reality, this is a question that Rockler customer service / technical support could answer more expertly.
I have a 12" deep cabinet, do I need 12" or 9" slides?
Brandon W on Jan 19, 2016
BEST ANSWER: It's been a while but as I recall the important measure is the length of the drawer and there is not a lot of tolerance for that. I ended up adjusting the length of the drawers to accommodate the slides. Their web site might be a better place to look.
I'm looking at a retrofit, which I know Blum does not recommend, but my wife wants these. Drawer opening depth is 22" and drawer is 20". Is there any way I could make a 19" slide work? Looking at the specs for a 21" I don't have enough depth. Suggestions or comments?
Paul M on May 12, 2020
BEST ANSWER: It may work to install the the orange drawer locking device 1 inch further away from the drawer front, I don't think this would cause a stability issue. Normally, this locking device mounts to the drawer front from underneath, but if you were able to move it one inch back, and still be able to screw it to the drawer bottom, then the glide would be able to lock. If your drawer bottom is very thin, like 1/4" mdf, then this may not be strong enough and you would have to come up with another way to secure the locking device. If it is 3/8" or thicker plywood it should work fine. Maybe buy one to see if it works. I used these with a retrofit in my kitchen, and had to make some other adjustments as well, but I was lucky on the depth.
Building 18” deep drawers and installing in a21 to 211/2” cabinet. What length drawslide do I need?
Jerry K on Jan 12, 2020
BEST ANSWER: Slide length needs to match drawer depth. Buy the slides before building the drawer so you properly accommodate the slides.
Can these glides be paired with the Tip on Push to Open mechanism?
adriana c on Nov 2, 2019
BEST ANSWER: I don’t think so. These are the top of the line soft close drawer slides. They do not have a push to open option. You will have to do some more searching for the push to open mechanisms.
Are 18” slides a true 18”?
Rusty B on Jul 13, 2019
BEST ANSWER: You should consult the documents linked to the drawer slide. the range of cabinet depth supported depends on inset or overlay drawers. I personally prefer inset drawer fronts and usually build the cabinet 1 inch deeper than the minimum. the rear brackets give you a range of adjustment.
How do I insert a drawer on the slides? I removed the drawer and I'm not able to insert it with the correct vertical alignment.
John W on Jan 31, 2019
BEST ANSWER: The drawer should just sit on top of the slides and when you push it in it will click into place. If the alignment has changed,. Each slide has a cam near the pin that fits into the back of the drawer that allows adjustment of height of the back of the drawer. Some of the latches (at the front of the drawer) allow multiple adjustment (up, down, left right). If the drawer is still out of alignment, then you should check the slides themselves have not been dislodged during the removal process.
is there a limit to how wide the drawer can be?
Jerry B on Dec 8, 2018
BEST ANSWER: I don't believe so. However, you will be limited by how much weight you intend to put inside the drawer. Also, depth is critical.
I am designing a nightstand that will have 1 drawer and the drawer front has a curve to the top (like a smile). The back will be open to allow light to pass through the front. Do you have to use the rear mounting bracket? Or is there another way to secure it?
Devon L on Oct 11, 2018
BEST ANSWER: The rear will need to be supported somehow. You don't need to use the bracket, but you'll need a bottom surface at the rear of the slide. You could put in a extra block of wood, so long as you've got about a 1/2" depth to drill the support screws into.
Can they be used in an outdoor kitchen?
Frank on Aug 21, 2018
BEST ANSWER: These Drawer Slides are excellent units. I don't see any reason they could not be used in a outdoor kitchen as long as they are not exposed directly to the elements. For the most part they are under the Drawer. I am not sure exactly how you plan to use them, but just keep them dry. It is important that the drawers be the exact length and I would also recommend that you purchase the two drilling guides. They make installation extremely easy. If you have other questions let me know. I think you will really like these units.
For the 15” slides should the drawer length (front of drawer front to back of drawer back) be 15”?
John B on Jun 12, 2018
BEST ANSWER: I’ve only done one project with Blum slides so I really can’t help. I do remember that I had many questions about the same thing and I thought that the instructions were very vague so I decided that I would never use Blum products again.
