Blum Tandem Full Extension Drawer Slides with Blumotion Rockler Undermount  Drawer Slide Jigs Dresser Build featuring Rockler's Dovetail Jig | Patrick Hosey How To Install Blum Tandem Undermount Drawer Slides | Tiny House Revolution
Blum Tandem Full Extension Drawer Slides with Blumotion

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.


Features:

  • 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.

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
BEST ANSWER: You'll need the 21" Tandems and you'll either have to cut down the depth of your drawer to 21" or remake the drawer box at 21" deep. Tandems come in 3" increments, not 2" like other slides. 9,12,15,18,21.....
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.
What is the clearance distance required from the exterior side of the drawer box to the inside face of the cabinet in a flush application? Typical drawer slides the clearance is 1/2" . What about these?
Brad B on Apr 24, 2015
BEST ANSWER: The drawer side clearance is based on the thickness of the drawer sides. So take the inside cabinet width minus 1 5/8" and that will be the inside dimension of your drawer. The maximum drawer side thickness is 5/8".
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.
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?

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 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.
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 slides..do 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.

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.
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.
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, as long as you have a separate drawer front to hide the extra space required at the bottom, and enough depth in the cabinet. I built an inset drawer using these slides, as reviewers have noted, take the time to read the instructions completely so that you understand the slides before you cut your first piece of wood.
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
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 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.
is it totally necessary to a have a 1/2 inch recess on the bottom of the cabinet to mount the hardware?the cabinet I want to use has no recess
Terry J on Aug 30, 2017
BEST ANSWER: Terry,
Sorry for the delay in answering your question. I followed the Blum instructions to the letter and my install worked perfectly. I did have the 1/2 inch recess.
Good luck.
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.
What is the minimum thickness for the back panels of the cabinet? I was planning to use 1/4 back panels but was wondering if it need to be thicker due to the back mounts.
JEFF J on Dec 29, 2016
BEST ANSWER: The slides are really intended for a Euro style, frameless cabinet. You can put screws through the sides of the slides and into the cabinet side. If you are doing a face frame style cabinet, just install a floater between the face frame and cabinet back for mounting the drawer slide.

OR

Put a floater on the inside of the cabinet back and anchor the supporting brackets there.

In either case glue the floater in place and shoot nails into the floaters from the outside.
What is the minimum width of a drawer I can use these on?
Joseph D on Jul 21, 2016
BEST ANSWER: From Blum's web site: Minimum inside width 170 mm (6-11/16") Note that this is the width inside the drawer box.
Do these come with the adjustable locking devices? Thanks for the help!
Micah D on Jan 8, 2016
BEST ANSWER: They come with the standard locking device. Not the adjustable locking device. These would be available at extra cost.
What thickness of wood can I use for 21 inch sliders?
S R on Nov 7, 2015
BEST ANSWER: If you are asking what thickness the cabinet boxes should be I'd recommend 3/4" ply. However, I suspect you are wanting to know what thickness works well for the drawer boxes. My recommendations for large kit. cabinet drawers are any of the following four: 5/8", 9/16, 1/2, or 7/16 . I particularly like 5/8" Baltic birch which I edge with solid wood (for looks). It's even possible to use 3/4" ply but the side clearance is especially tight at 1/16th and the directions don't refer to 3/4". One thing to understand with this model/brand is that the thickness of the drawer sides has a direct influence on what the side clearance needs to be. Most other drawer slide hardware requires 1/2" clearance on each side no matter what thickness the drawer box is made of. The directions have a schedule that tells you how much to deduct from your drawer width depending on how thick your sides are. Example: 24" cabinet opening width with 5/8" thick sides (-) 3/8" = 23 5/8" drawer width. I've come to understand that the measurement from the inside face of the drawer and the cabinet wall is 13/16" no matter what stock thickness the drawer is made of assuming the stock is within the 7/16" - 5/8" range. I strongly suggest looking at the directions before building the drawer boxes. They also call for 1/2" clearance from the bottom of the bottom to the bottom edge of the sides. This allows for the quick release hardware. Another lso,, there shouldn't be any "ears" on the back of the drawer boxes. (A lot of drawers are made with overhanging side ends due to the drawer back being slipped into dados on the sides). Such "ears" would be in the way of the adjusting pins. Again, read the directions before building the drawers and take your time. Once you get through the first one I think you will like them a lot.
I am looking to buy this product. My drawer is 15 inches long and the cabinet is 18 inches deep. What length drawer slide would I need to order?
A shopper on Aug 2, 2015
BEST ANSWER: If the inside cabinet depth (front to back) is a minimum of 15 13/16ths to 17 1/2" max you can use the 18" drawer slides with 15" drawers. They come with an "L" end bracket that attaches to the inside back of the cabinet but you probably won't need to use these if you attach the drawer sides to the sides of the cabinet. I do this with wooden blocking and I feel that this adds a lot of stability to the assembly.
The Inside Measurement is 23" and the Drawer side is 19" what slide do i need?
Jim H on Jul 20, 2018
BEST ANSWER: Based on those measurements, I would go with the 563H5330B. These are built for 5/8” width drawer sides. The main difference between the 563H and the 563 is that the 563H is long enough to attach the back to the rear bracket.
Drawer length or depth; measured from inside the drawer box or outside?
Rick P on Jul 4, 2018
BEST ANSWER: Outside. Usually there is a tab on the bottom slide that has to be routered out for on the back of the drawer box. Looking up specs is a good idea as all hardware is just a little different.
