Rockler Router Table Box Joint Jig

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
  • 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.

Table Router Box Joint Jig
I went into this knowing that I would need to make some small mods to make this jig work with my old Craftsman router table. I had to lengthen the two slots for the 5-star knobs by about an inch to allow adjusting the jig forward toward the router bit. The jig's two sleds that run on the table's router miter slot were about 1/8" too high so I took an old table saw miter bar that fits the table perfectly and drilled it to attach the two 5-star knobs & bolts. Also had to modify the router table by cutting two one-inch long slots to allow for adjusting. Works great after that! Great product!
Modified an old table saw miter sled bar
Elongated slots to allow adjusting the jig toward the router bit.
Able to adjust for perfect cuts now!

Excellent jig for the money!
The Rockler box joint jig is absolutely perfect for my needs! Only thing I needed to do was drill a hole for the rotor lift. Was an easy fix! Action is nice and smooth, I put .100 shim under the sacrficial fence to assure easy sliding movement. Joints were perfect right out of the box!, no adjustment was necessary. I am very pleased with this product.

router table box joint jig
This is my third Rockler box joint jig over the last 10 years. I constantly use them on big and small projects with excellent results. Once set up they are easy and fast to use.Unfortunately they wear out. The sled could be a little taller on the latest model. I would recommend it.

Box Joint Jig
I have a dovetail jig already and wanted to add the box joint to my jig assortment in case I decided to make something where box joints would be more appropriate.

When the jig came in, I immediately set it up for my router table and found it to be well fitting and solid when clamped in. Although I have not used it yet, I'm looking forward to it. If it's a Rockler product, I expect it to work as advertised.

Well Worth the Money
This jig is fantastic. I just finished making eight box drawers for an oak desk I’m building. They fit together perfectly and really make each box look like it was professionally made. I love it.

How do you make the first cut?
Ivan T 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 this work on a kreg Precision Benchtop Router Table, prs2100?
Lynn V on Apr 24, 2018
BEST ANSWER: Yes thats what I use.
Will it fit on a Bosch RA1181 router table?
Bill on May 16, 2018
BEST ANSWER: It should be adjustable to any router top as long as it has a miter slot.
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.
Does this fit a DELTA 43-505 Router/Shaper?

What is the largest size box you can make with this jig?
S N on Jun 15, 2018
BEST ANSWER: Actually you are limited to the overhead room in your shop, provided you make each cut with the piece tightley against the brass guide. I have done a 2 ' x 4' box with my jig. I guess it also depends on how accurate your set up spacer is. Lots of luck!
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.

Rockler Router Table Box Joint Jig

Rockler Trim Router Table
Rockler Trim Router Table
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.
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.

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!
Will this fit a Bosch Router Table - RA1171?
Roberto P 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
Do you need more than one superficial backer board. As I read in the book it says to make 2 other backers so you have 3 backers of the 3 sizes of the pins, ?
William F on Jan 20, 2019
BEST ANSWER: Yes, you need one for each pin size. First so that each will fit snugly around the guide pin you are using and second to avoid tear-out in your workpiece. I would also recommend a new backer when you change the depth of cut to avoid tearout at the top of the cut.
Would this work on my Bosch router table?
B J on Nov 19, 2018
BEST ANSWER: It should. It works fine on my Kreg table.
Where can I find a class to learn this?????
Al on Sep 23, 2018
BEST ANSWER: I'm not aware of any classes being offered but you could check with your local Rockler store for one-on-one set up and use instructions. They're usually very helpful.
what is the best router bit to use with this jig?
Paul B on Sep 23, 2018
BEST ANSWER: I use upcut spiral bits. They can be kinda spendy, but a clean cut is important.
Will this jig work on a craftsman router table?
William B on Aug 17, 2018
BEST ANSWER: As per the specs of the box joint jig, Near edge of router table's miter track must be between 4-1/2'' and 6-1/4'' from the center of the router bit. Also the miter slot must measure 3/4 wide by 3/8 deep.. I have a royobi router table and the first spec was alright but the miter slot wasn't. I needed to modify the miter slot and rout a 1 inch slot to accept a rockler miter bar.
Would this jig work to put through dovetails in the face of the wood I am using to make a flag case?
Jeffrey L H on Jul 19, 2018
BEST ANSWER: Sorry this jig is only for finger joints. If your looking for a jig I do recommend checking out the dovetail jigs available at Rockler. They have different varieties. Hope this helps.
I have rocklers router table and the miter slot is farther away than the recommended distance by 1/8” -1/4” will I have a problem?
George W on Jul 16, 2018
BEST ANSWER: Not sure I understand your question but mine works great. I suggest you prep some scrap wood and play with it until your sure you understand how it works. Good idea to never trust instructions but follow them through at least once. Rye
How deep can slots be cut in the material using a stander router bit?
C. H on May 9, 2018
BEST ANSWER: Per the downloadable directions the maximum thickness is 1". That is also the length required for the fingers. Depth of finger cut is the thickness of the wood being used plus a very small amount so you can sand the fingers flush after assembly..
Anybody use this jig on a Rockler convertible router table?
Stephen L on Mar 14, 2019
