Rockler Cross Lap Jig

Quickly cut the lap joints for latticework, wine racks, torsion boxes, shoji screens and more!

Item #
88% of 100

When you need to cut multiple lap joints with uniform spacing, reach for our Cross Lap Jig. Screw it to your miter gauge and use it with your table saw and a dado stack to cut the half-lap joints for anything with a wooden grid: lattice, wine racks, grilles/mullions for glass doors, and torsion boxes for your workbenches and table tops. The jig's indexing key is width-adjustable for stock ranging from 1/8'' to 3/4'' wide. The distance from the indexing key to the blade determines the spacing of your grid, and is easily adjustable with the ergonomic knobs. Simply make your cut, push the key into the kerf you just made, then make the next cut.


  • Machines the interlocking dadoes for cross lap or half-lap joints
  • Great for latticework, wine racks, torsion boxes, shoji screens and more
  • Indexing key for fast, repeatable cuts, and precise spacing in fixed increments
  • Width of indexing key is microadjustable for stock from 1/8'' to 3/4'' wide (to match width of dado)

This jig is AMAZING! Super easy to use and set up. I’m not mathematically inclined but once I understood how the jig worked the setup was a breeze. Great accurate results. I’m trying to come up with more designs I can use it on.

Cross Lap Jig review
I purchased the Cross Lap Jig to make wine racks to insert into some of the cabinets I make for charity auctions. The detailed instructions were very helpful. Once the jig was assembled I proceeded to make my first wine rack. The jig performed great the joints were dead on. I recommend this product for anyone needing to make repeated lap joints the jig is a time saver.

Woodworking Experience:
Love the Jig... the plan dimensions are wrong on the coffee table
The Jig is flawless... really works well.

However, the plans for the Coffee table are wrong and need to be corrected by Rockler for the dimensions on the legs...

Don't be fooled... the legs (3) should be 15 1/8... not 12 1/4 as per the material list... VERY FRUSTRATING WHEN YOU CUT TO THE PLAN

It works as a box joint jig!
I originally purchased it for making box joints because I like the fact you can “dial in” the jig. I was able to use a pair of calipers to dial it in to the dado set I was using. It does a great job making box joints! I can’t wait to do more projects with it.

Can this jig also be used to make finger joints or box joints? It seems like it would work for them as well.

Can you this to make box joints with this jig?
andy v on Aug 9, 2018
Is the jig fence replaceable? It seems it would not take to long to fill it up with notches.
Duane H on Aug 12, 2018
BEST ANSWER: We do not sell replacement fences. However, there are instructions and dimensions to make a new fence in the product manual.

Our Rockler T-Slot Cutter Router Bit - 5/8" Dia x 3/16" H x 1/2" Shank (Item 26099) will provide the correct slot for this jig.
Can this jig be used with a router table that has a miter slot? What if you took multiple passes with a straight bit and increased the depth on each pass?
DONALD R on Feb 3, 2019
Can I download the calculator for the lap jig?
Gdocanndoc G on Aug 9, 2018
BEST ANSWER: The cross lap calculator is currently hosted online only.
Am a newly woodworking. For scale from 1 to 10 how hard is this item to use?
ruben on Nov 6, 2018
BEST ANSWER: At 5. Actually a walk in the park.
Can you use this with a sliding miter saw that has a depth-stop, or on table saws only (my table saw's miter gauge is pretty bad)?
Jim A on Jan 11, 2019
BEST ANSWER: No, only table saw because the cuts are made on the bottom.
Does this work on right tilt saws?
steven s on Jan 2, 2019
Does this jig require a dado stack or can it be done with a single blade and multiple passes?
Brian on Oct 14, 2018
BEST ANSWER: It can be done without the dado. It will take a ton more work without the dado and your margin for error is greatly increased..
I only have a table saw that doesn’t accept a dado blade. Would it possibly work without a dado or would it be a pain?
TOM C on Mar 8, 2019
BEST ANSWER: I think it would be a waste of your money. The jig is meant to be attached to the miter guide. You might be able to clamp it to the miter guide, but you wouldn’t be able to reproduce the exact width of cut or spacing you get by permanently attaching the jig to the miter guide.
I only have a table saw that doesn’t accept a dado blade. Would it possibly work without a dado or would it be a pain?
TOM C on Mar 8, 2019
BEST ANSWER: It absolutely can be done with this jig. A dado blade is not required. If you are not doing a large volume of work. You won’t find it to be a pain.
Can this jig be used to make dentil?
Craig T on Feb 20, 2019
BEST ANSWER: It's basically a dentil maker as shown in the photo above.
Can you purchase replacement fences ?
John B on Jan 29, 2019
BEST ANSWER: No. However there are instructions that come with it on how to easily make your own.
Can you attach the jig to a mitre sled? I have the incra express sled with 1000HD can I attach the jig to the miter guage that is in the Incra Sled?
Pete on Sep 30, 2019
BEST ANSWER: Not sure. I owned a Kreg miter gauge which just won't work, so I bought an INCRA 27V and mounted it to that.
Regarding the key assembly, what is the height of the keys? I often create shallow half laps for picture frames and am concerned the key height would be too tall.
John A on Mar 22, 2019
BEST ANSWER: I measured with set-up block - almost exactly 1/4".
Again as others have asked without a reply. Can this be used on a Router table? I ask this as i am getting your new plunge saw, table and track and getting rid of my table Saw
Donut on Feb 27, 2019
BEST ANSWER: This jig is designed to make box joints and half-lap joints easily on the table saw or router table
What is the width of the miter gauge track slide slot?
BENJAMIN H on Dec 30, 2018
BEST ANSWER: US standard saw or router track slot: 3/4" wide x 3/8" deep.
Can this be used for finger joins?
Carl on Nov 17, 2018
BEST ANSWER: No, because the edge of the wood has to be on the table saw top, it would be very hard, if not impossible, to hold a long board vertically against the jig and then slide it through the saw blade. It would also result in huge fingers. Rocker, sells a variety of finger joiner jigs.
Can this be used as a box joint jig as well?
DAVID C on Jan 22, 2019
Can this jig be used for other than pure perpendicular joints?
