Rockler Router Table Box Joint Jig

Item #
76% 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
  • 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.

Great jig!
This is a great jig value for making box joints. Took less than 10 min to assemble out of the box, instructions are very clear and easy to follow. Within minutes of setting up, I had made my first box joints and they fit like a glove! Highly recommended!

I love this jig
I bought this jig to make quick painless box joints.
After reading the instructions (wrong first time I might add) I was able to perfect the box joints & they are tight as they should be.
The only complaint is they could have included the piece of MDF for the 1/4" & 3/8" pieces but I had a piece of MDF laying around so was not a problem. Overall I am very happy with this jig.

Woodworking Experience:
Beat any other way I have tryed
This product is a dream come true. It makes clean straight 1/2in, 3/8in and 1/4in box cuts every time if you set it up right. It is so easy to use but you have to read and follow the instructions. Now for some of us, like me this is a last resort. The slides are nice and the brasses are the right size. Dust collection might be the only problem with this unit. But, for making a box joint it is great.

Woodworking Experience:
Works for small jobs
Needs a sharp router bit (I used up-cutting spiral and standard and both seem to work fine). You'll need to definitely use backing if cutting plywood and even then, you might get some tear-out. For small projects like small boxes or smaller drawers it's fast and easy to set up. Works great with solid woods. But use a table saw and finger-joint blade for bigger projects and to avoid tear-out on plywood. At least in my experience. Roy

Woodworking Experience:
The jig was easy to put together,easy to learn how to adjust to the three different sizes of the box joints and easy to make good tight finger joints. It only took me two attempts to make good looking and good fitting box joints. Reading reviews, some people had trouble getting the jig to fit on their non-Rockler router tables, well the jig fits and works smoothly with my Skil brand router table model #RAS900, which is a very inexpensive router table but works well for what I'm using it for.

BARRY D on Jul 5, 2018
We tried making our own jig, but it didn't seem to be precise enough as some joints fit and others didn't. We are hoping the metal keys will provide the stability we need for the precise cuts.

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
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.
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?

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!

Roberto P on Aug 19, 2018

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.

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
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!
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..
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.
How do you stop the jig from sliding left and right on the table? Tighten 5 star knobs doesn't help. Bosch table 3/4' slots
Guy L on Jul 25, 2018

Do you have any pictures of your jig & your router table? This should not be a problem.
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
