80% 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

Woodworking Experience:
Great Jig
Thought it was a bit pricey for what it does, but once I set it up and used it I was quite impressed. Not only was set up easy, although I did have to modify it a bit to fit my old Craftsman router table. I was able to start making clean, consistent, and repeatable box joints with a minimum of fuss. Well worth the money. I would definitely recommend this product.

Precision and Simplicity
Using a router bit rather than a table saw dado blade cut cleaner slots for the box joints and this jig made things so simple. The set-up was very easy and the precision was perfect.

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.

BEST ANSWER: Yes thats what I use.
Will it fit on a Bosch RA1181 router table?
Bill 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.
Does this fit a DELTA 43-505 Router/Shaper?
dennis on Aug 26, 2018

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.
Will this work on a Rockler Trim Router Table? Thank you!

Rockler Router Table Box Joint Jig
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.

O T on Jul 14, 2018
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
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!
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?
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
I have the JessEm Mast-R-Lift II Table (complete package). Can this jig be modified to work on my table? The near edge of the miter track is 6 3/4 inch from the center of the bit.
James M on Sep 17, 2019
BEST ANSWER: Yes you should be able to use this jig as mine is the exact same distance on my router table.
There is a little bit of play room & it works perfectly on mine. Hope this helps. Happy routing.
My router miter slot is 3-1/2" to center of router bit. Can this jig be used or modified to work with my table?
Tim K on Jul 2, 2019
BEST ANSWER: Yes, but I had to modify the screw hold down slots on my Rockler jig in order to accomodate my Bosch router table. I added a one inch slot at 45% to the existing slot, so I could adjust it left or right.
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?????
Sarge 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..
