Rockler XL Router Table Box Joint Jig

Item #
64% of 100

Now you can machine bigger box joints for large-scale projects on your router table. Build large chests, guitar amps, cabinets and more! Just use the knobs to secure the MDF base of the jig into the miter slot of your router table—the sturdy steel sled then lets you guide the workpiece past the bit with complete control. The jig includes precision-machined aluminum indexing keys to give you air-tight joints with either 1/2'' or 3/4'' fingers. The vertical face of the sled features two sacrificial MDF boards that securely sandwich the workpiece and provide backup support for reduced tearout. Larger pieces can be supported easily by adding a 1/2'' piece of material to the left and right side of the jig platform. The jig is easy to setup and detailed instructions are included.

  • Easy-grip rear-mounted handle makes feeding your stock easy and ergonomic
  • Sturdy steel frame handles heavy materials
  • Stable MDF platform has low-friction melamine coating for added durability and easy cleanup
  • Easy-grip knobs lock the base into your miter slot.
  • Fits standard 3/8'' x 3/4'' miter gauge slot
  • Use with up-cut spiral bits for the cleanest cuts without blowout (see #63008 and #57813, sold separately)
  • Requires a straight router bit to match the size of the indexing key.
  • For compatibility, the near edge of your table's miter track must be between 4-1/2'' and 6-1/4'' from the center of the bit.

Woodworking Experience:
Most box makers need one of these. ??
My XL box joint jig has met all my expections and I can certainly recommend it to average woodworkers. The actual instructions supplied got me started but I needed to get on You Tube to watch the actual operations. A video in the package would have saved me some time. The Rockler video only did the first step. Would have helped to see all four sides completed! Jig should accomadate smaller sizes also!

Great box or finger joints
I have a smaller jig that I bought from Rockler some time ago and it has served me well. The problem I had with it is "wood chip cut out" where the back side of the cut would splinter leaving small chips of wood missing at the corner of the joints.

My first use of this jig and the cuts were perfect. This will save me from having to do a lot of extra work.

Woodworking Experience:
got my jig a few days ago. Have only done test cuts so far. I am happy with it, but it could be improved with better instructions. I am using on a Porter Cable router table. The bars that lock it into the miter slot were too narrow. I had to epoxy shims cut from a tin can to make them lock firmly. I think Rockler should offer a set of bars so as to be able to make smaller box joints.

Solid and Reliable Product
I've made several boxes with this jig & find it to be easy to use, very accurate and a safe way to cut 1/2" & 3/4" box joints. Recently used it to build a 2' long x 1.5' wide x 1' foot high red oak box out of 3/4" stock which came out perfectly and took very little time to cut the joints.
The included instructions are ok , but a detailed video would be nice and would save time; -vs- the trial and error needed to get joint spacing and stock width absolutely correct.

XL Jig Review
Having used the XL Box Joint Jig to make a strong jointed wood working tool box, (roughly the size of a blanket box ) I was quite impressed with the way it performed. I would certainly recommend it to anyone!!

Great But...
I love the jig but.. If you are very much a novice you should becareful about this jig. I got it home and started to put it togeter. The instructions for assembly are actually how to use it. There are no assembly instructions at all besides a nice blown up diadram. It is not hard to figure out though. The pieces look like they should just go together and work right out of thre box. It does not. Many of the pieces need you to drill pilot holes and please do this very carefully. After getting it all finished I noticed that when snugged up to work both of the uprights where not at the right angles. I needed to get out a sq and fiddle with all of the parts until each was at the correct angle to the table. Mine started out about 1deg of from front to back and 1deg from left to right. I fiddled with one to fix it but had to add a shim on the other part. If I was a novice to this type of jig and just assembled it and tried to use it my project would not fit together correctly at all. There would have been gaps every where.

After the fiddling I got it all correctly aligned and it should work just fine. I recommend this jig for sure but check all of the parts as you do your assembly. It will then work great. I will be using it for larger works like blanket chest sized connection.

I have the Rockler Router Table Box Joint Jig Item #: 29502, is there any way to add the 3/4" guide to this smaller unit?
Darrell H on Dec 30, 2015
BEST ANSWER: I do not have the same jig you have (29502). I have the big brother of yours. It comes with 1/2" & 3/4" but does not have the small ones that you get. So I guess we both should spend more $$ and get both sizes. Must be what they wanted! But I got mine to make lager things like long blanket chest type things. I think mine could adapt to the smaller keys if I could purchase just the keys. Good luck. I find that I go to the store and someone there usually can come up with a fix. Yours might be more trouble due to the face you might need to enlarge the dado that holds the key in place if you could buy the 3/4" key from my jig.
What distance is needed between bit hole and miter gauge slot?
Gerry on Apr 29, 2015
BEST ANSWER: Roughly speaking, the range of distance from the center of the bit hole to the miter track is approx. 5" to 7.5". The hole itself is 1.5" wide so, depending on the diameter of the router bit used, the actual range is somewhat greater. You could always open up the bit hole a little if your track is nearer to or farther from the router bit.

Can you cut box joints in a 24" high x 50" long board?
Larry W on Jan 2, 2016
BEST ANSWER: I have cut cedar boards up to 34" in length and felt I had reached the limit that could be cut reliably. Width is less an issue if you have adequite wiidth on your router table or add a solid extension.
Do you have 1/4" and 3/8" guides for making smaller box joints?
D B on Mar 2, 2018
BEST ANSWER: Yes, but I have not used it yet.
How to loosen up the joints? using the 1/2 bit and 1/2 key, I used the 1/2" spacer bar and made the cuts per the instructions and did the mating pice sing the firt cut. The joints were super tight If i wanted to loosen the fit up a hair, would puth eh keu fence closer to or further away from the bit? And how would this affect the spacing as far a s full pegs and valleys. I.E. 1st iiece starts and ends with pegs and mate starts and end with valley.
CHIP P on Nov 30, 2016
BEST ANSWER: You can't loosten the fit of the joints unless you really got wild and made a first pass, then a slightly offset send pass; or had a bit that was just a hair oversized. The tight fit is desired. Adjusting the sled closer or further to/from the bit only changes the location of the first cut. All subsequent cuts are spaced by the guide bar and you can't change the fit other than the two methods mentioned.

You can, and should, adjust the first cut if you are going to end up with a lady cut of less than .1" either on the front or side. If you have to adjust for that, I recommend that you always move the fence closer to the fence to make the adjustment on the first piece.
can you cut all 4 sides of a box at one time (one edge at a time of course)?
PMB-BL37759-Barbara L on Jul 17, 2016
BEST ANSWER: There is a maximum to the thickness area. You can not cut all 4 sides any way. Because the frnt and bck match but the ends have a different cutting pattern or the box will not go together. I guess you could try and cut the matching sides. But this jig makes things so easy when you get it correctly set up that it moves quickly through the 4 sides. Basically after set up you just place the board in the jig and cut then step it over an repeat until you have done the full length. Then you do a small change for the 2 other ends and repeat the cutting. Moves very quickly. Make sure you spend the time with this jig like any others to be real familiar with the workings. Then all will be easy and your results will be good. Make sure you do not lift up on the ends or cut before you are set properly. Again then you will be very happy with your results!
Can these jigs be used to make a single 3/4 dado cut?
1quickgt 1 on Jul 17, 2018
BEST ANSWER: Yes they can. The spacer bar would have to be removed (just 2 screws) and that would allow you to make the dado anywhere on the piece
Does this jig just do box style joints or is there a guide for dove tails as well, I'm looking to do blind dovetails at 48 inches long can this be done with this jig?
Chris B on Mar 18, 2018
BEST ANSWER: This jig is designed for 1/2" and 3/4" box joints only.
Anyone used this on a kreg router table package. Any particular issues?
Stuart C on Jun 24, 2017

Does this cut only 1/2 & 3/4", or can it be set up to cut smaller sizes like 3/8" or smaller?
Brenda S on Aug 27, 2015
BEST ANSWER: This can only be used for 1/2 or 3/4" size, for smaller sizes the http://www.rockler.com/rockler-router-table-box-joint-jig is needed.
Can this jig be used on my portable table saw to cut 3/4" box joints with my dado blade? If not, does Rockler make a comparable jig for the table saw?
A shopper on Apr 30, 2015
BEST ANSWER: This jig was only designed to work on a router table.
