Rockler Router Table Box Joint Jig

Make strong, tight-fitting box joints on your router table—great for small- to medium-sized boxes!
Item #
84% of 100

Box joints are strong and attractive, and with the help of our Router Table Box Joint Jig, they're also straightforward to make. This jig uses precision-machined solid brass indexing keys to ensure uniform finger spacing and an airtight fit. Keys are included for three finger widths: 1/4'', 3/8'' and 1/2'', and can be used with stock up to 3/4'' thick. The smooth-sliding sled features long ''skis'' that keep it square to the bit and tabs on the bottom that stop the sled at the end of the cut. Lock it into the miter slot of your table with our comfortable Easy-to-Grip knobs and you're ready to rout.


  • Solid brass indexing keys ensure uniform spacing and tight finger joints
  • Indexing keys store neatly in slots behind the sled
  • Comfortable ergonomic knobs lock platform into 3/4'' miter slot
  • Sled is made of durable glass-filled nylon, slides smoothly and provides ample support
  • Sacrificial MDF fence face helps control tearout
  • Dimensionally stable MDF platform has low-friction melamine coating for easy sliding and durability
Notice: Requires a straight router bit (sold separately) to match the size of the indexing key. Up-cut spiral bits deliver the cleanest cuts and help prevent blowout.

Box Joint Router Jig
Works well. Instructions could be better for setting up the cuts. I had a bit of a problem getting the edges to be flush on all four corners. Must be operator error or inability to understand the instructions (even with pictures!). I like that it has spacers for three sizes of router bit.

Woodworking Experience:
Works Very Well
This jig is made well and the way it grips my portable router table is neat and effective. This jig works best on thinner, lighter woods. When trying to cut deeper slots in stock, I have had trouble with the wood "wandering" - a common issue for routers. It didn't always come out great when trying to make several passes either, but clamping the wood stock to the sled helped that a lot. Required a lot of trial and error for me, but I have made a couple really nice boxes with this jig.

How do you make the first cut?
Ivan on Apr 30, 2018
BEST ANSWER: You first need to make your three spacers 1/4, 3/8, and 1/2 inch for the setup between the brass bar and the router bit. first slide piece against bar and cut. next put the spacer you made against tthe brass bar, and the next piece against the spacer and then the rest is just cut .
Write-up says for "3/4 inch miter slot". Does it mean 3/8?
ChetP on Apr 9, 2018
BEST ANSWER: 3/4" Wide, 3/8" Deep miter slot.

Will it fit on a Bosch RA1181 router table?
Bill Carmichael on May 16, 2018
BEST ANSWER: sure will
This jig fits nicely in the slot on my Bosch router table but tightening the five star knobs only stops the guides from moving on the jig. It does nothing to stop the jig from going side to side in the table slot. Is there some other piece or part I need to stop the guides from moving in the table slot?
BamaTony on May 16, 2018
BEST ANSWER: Add some tape the slot. It will tighten it up.
Do you sell replacement sacrificial fences?
Patrick L on Jan 12, 2020
BEST ANSWER: They don’t sell them pre-cut, but they are quick and easy to cut from MDF, and I have found that I like to cut them a little taller than the one that is provided.
Does this fit a DELTA 43-505 Router/Shaper?
dennis on Aug 26, 2018
BEST ANSWER: Sorry I have no idea if it will work, I use it on a Kreg router table
Are the indexing Keys compatible with the old rockler box joint jig?on that model, the indexing is done with long bars that are a pain to store as to swap out. The keys look to be a smart enhancement, but I don't want to buy a whole new jig. And if they are, can I purchase the keys by themselves?
Douglas C on Jun 25, 2018
BEST ANSWER: Unfortunately I have no experience with the older jig, so to be fair I cannot accurately answer your question.

O T on Jul 14, 2018

S N on Jun 15, 2018
BEST ANSWER: The only thing limiting the size would be the size of your lumber.
What is the best router bit to use with this box joint jig? A up cut or down cut spiral bit or a straight bit?
lester m on May 16, 2018
BEST ANSWER: Upcut Carbide bit. Steel bits will dull and overheat quickly.
Will this work on a Rockler Trim Router Table? Thank you!

Rockler Router Table Box Joint Jig

BEST ANSWER: The Box Joint Jig anchors to a 3/4" miter track, which the Trim Router Table does not have. You may want to consider the Rockler Convertible Benchtop Router Table.
Would it be possible to get a ¾" box joint, by using the ¼" slot three times?
Craig M on Apr 26, 2020
BEST ANSWER: I think this would be very difficult to be successful. Rockler sells a larger version that is capable of 3/4 joints.
Rockler XL Router Table Box Joint Jig
Sturdy steel sled lets you machine heavy-duty box joints on your router table!
Item # 50322
I have a woodpecker large router table 27'' X 43'' top, from the center of the bit to the inside of the miter slot closet to the bit is 6.750''. It says it needs to be between 4.500 and 6.250'' will I need to do some type of modifcation to the jig to make it work? And if so is the jig large enough to be able to do so? I do not want to buy it to then find out nothing can be done and therefor have to go thrugh all the hassle of returning it THANKS.
Grizz on Nov 22, 2018
BEST ANSWER: There is 7/8" extra base at the back end, you could extend the slots by 1/2" but that wouldn't leave much for the adjuster nut to clamp down on. The base is 3/8" (I think) HDF so you could make a longer one using the hole patterns from the original.
Will this jig work with my Bench Dog router table?
Dennis S on May 4, 2018
BEST ANSWER: Will work with any router table as long as the tracks are the correct distance.
Will this jig fit on all router tables?
Larry H on Jun 30, 2018
BEST ANSWER: This jig should work with most router tables that have a 3/4 inch track. Easy to set-up work and the brass fingers are accurate. Rich M
Can the bits be bought seperate I dont think will be needing all 3 of them only looking for the 3/8 in and will a regular 3/8 router bit work ?
S A on Apr 22, 2020
BEST ANSWER: There are no bits with this kit so you can buy the ones you want to use. They recommend up spiral bits.
Is tear out a problem with this jig?
Stephen L on Mar 17, 2019
BEST ANSWER: I've used it on Hard Maple, Walnut, Red Oak without a great deal of difficulty. Make sure to trial on scrap wood and make sure adjustments are TIGHT (for repeatability). Take it slow and easy. I like the way it uses TWO miter slots feeding into the router bit for stability. Results were better than I'd had using a similar jig (one miter slot) on my table saw. I believe a worthwhile buy considering the quality of the parts. The board on the jig face can be replaced when and if needed.
Does this work only on Rockler tables? Can I use it on my Craftsman table?
Arne S on Jun 15, 2018
BEST ANSWER: This works fine on my Kreg table. As long as the table has a standard mitre slot and the slot is no more than 7 inches from your router opening or the position of the router bit when it is above the table.
Will this work with a WoodCraft table?
Don D on Jun 25, 2018
BEST ANSWER: I'm not 100% sure of this but it should work on any router table with a groove for a miter gauge on the front edge. That's where the jig mount/secures to the table.

Good luck!
Hi, just to clarify something. I'm in Australia and am having trouble sourcing mitre track from suppliers who send T track instead. I definitely want the mitre track (the one shaped like a "U") right? Not T-track that has a top opening of 3/4"?
KangaTroy on May 14, 2020
BEST ANSWER: The open channel in Miter Track (Rockler item 48037) is 3/4" wide and 3/8" deep.
What length bits must be used?
Wesley C D on Apr 20, 2020
BEST ANSWER: The length of the bit is only as important as the depth of cut you are making. If you cannot achieve proper depth of cut desired by making adequate adjustments...get a different bit.
How do I stop the tear-out and chipping? I am using Maple and Oak with a 1/2" bit on a 5/8" thick piece
Rick F on Apr 6, 2020
BEST ANSWER: I use an MDF backing plate and very, VERY sharp bits. If you change bit sizes don’t forget to change the backing plate.
Will this work on a Kreg PRS1045 Precision Router Table System?
Michael C on Mar 14, 2020
BEST ANSWER: Don’t know. I have a Bosch router table which required a modification of this Rockler jig. It works good with the modifications I made.
Will this work with a dewalt compact router?
BIGGUY19 on Feb 18, 2020
BEST ANSWER: I don't see any reason why it wont. If the router is mounted to the table correctly. If the router bit comes thru
the table. It's workability is a function of the table you have.
can this be used in the portable router table?
ryan a on Nov 29, 2019
BEST ANSWER: In my opinion the answer would be "no", although every woodworker's skills vary. I used it with a 1/2" bit and it took all of my attention working with walnut … and my table is part of a larger configuration that also contains my table saw (i.e. well secured and very solid). I wouldn't want to worry about table movement when your hands are a few inches away from a bit going 15-17,000 rpm. Hope this helps.
Can the sacrificial fence be replaced with a taller one (6”) so longer cabinet sides can be secured while being cut?
Eric R on Aug 11, 2019
BEST ANSWER: In theory, yes. There is no reason a taller fence cannot be installed. However, keep in mind that this jig is really designed for small piece work. You are dealing with plastic runners which are not super stable for larger router cuts.
Will this fit a Bosch Router Table - RA1171?
RSP on Aug 19, 2018
BEST ANSWER: I have a Bosch RA1181 router table and the jig fits fine in it but make sure that it is properly tightened as specified in the installation instructions.
Will router and jig handle bamboo flooring?
David V on Jul 2, 2018
BEST ANSWER: Possibly, this jig is small, so if the pieces of flooring aren’t too long it should work. I find if the work pieces are over two feet long it’s difficult hold them in the jig to get accurate cuts.
Will this work on a Jessem router table?
Shawn on May 28, 2018
BEST ANSWER: If the Jessem router table meets all the specs laid out in the literature it'll work
