Rockler Perfect Fit Dado Jig with 50'' All-In-One Low-Profile Contractor Clamp

The ultimate package for cutting perfectly fitted dados for a wide range of plywood thicknesses—no undersized bits required!
Item #
76% of 100

This package combines the easy clamping action of our best-selling All-In-One Clamp Guide with the precise dado-cutting capabilities of our Perfect Fit Dado Jig, designed to work specifically with this guide! With just an ordinary 1/2'' bit, the smooth-sliding Perfect Fit Dado Jig cuts tight-fitting dadoes for stock up to 1'' thick. The dado width is adjusted without detents, so it's perfect for plywood that is thinner than the nominal thickness, and for lumber that's been planed to an odd size—no need to buy an expensive undersized bit!

Operation is simple! Once you've set your thickness with the scale, just run the first shoulder of the dado with one edge of the jig riding securely in the groove of the All-In-One guide, then flip the jig around and run the other shoulder. The result is a tailor-cut dado that fits like no other. Once the jig is set, you can machine all your dadoes for that thickness without having to reset the jig.

  • Scale is calibrated for use with a 1/2'' straight bit
  • With a 1/2'' bit, jig can machine dados from 1/2'' to 1'' wide
  • Any straight bit can be used, but the user will have to account for the different offset from the edge of the dado sled. This means you can use a 3/8'' straight bit for 1/2'' dados, or a 3/4'' straight bit for wider dados
  • Hooked channels interface neatly with our All-In-One Low-Profile Contractor Clamp (e.g. 32777, sold separately)
  • Capable of working with any straight edge by butting directly against the edge rather than hooking
  • Knurled knobs and laser-etched scales make it easy to adjust the offset for the second shoulder of your dado
  • Made of sturdy, low-friction ABS
  • Pre-drilled to fit most routers with a standard 3-hole pattern, and can be easily drilled to fit other routers
  • Includes detailed instructions
  • Made in USA

50'' All-In-One Low-Profile Contractor Clamp

Now with lower profile and wider jaw for more stability! Wide lever handles and a click-lock sliding jaw make it simple to position and secure the guide for use with circular saws and routers and as a fence for your table saw or drill press. A very low 17/32'' profile body and flat top allow many applications without obstructing tools. Easy-to-read full color measuring scales enable outstanding accuracy anywhere along the clamp. Onboard T-Tracks fit select clamp accessories, sold separately. Rigid, lightweight construction. 2-1/2'' wide.

I really like it. Works well. My only problem was to make sure the screws that control the tape is tight because the will losen. But overall it’s great

Great for long cuts in heavy material
Bought this for a large bookshelf I had to build. My dado cuts were perfectly straight. The shoes glides easily over the 48" material I was cutting. Highly recommended and worth every penny.

I need to make sliding dovetail dados in some cherry-wood boards for a custom bookcase and have very little room for error. This looks like just the setup I need.

Michael J on Jul 17, 2018
I prefer to cut dados with a router and this tool apppears to make it easy to cut a consistent dado every time. I am all about the right tool for the job.
Dan H on Apr 20, 2018
I am thinking it will meet my requirements for continuous dado for a multilevel shelve system as per Youtube.
Mark S on Apr 11, 2018
I have a limited vision, and arthritis in my hands and wrists. I have worked with Roger tables and routers for a long time and I'm finding it a little difficult now to hold the tools securely. The state or jig shut up seem to be the most secure to help me safely create dadoes especially on long runs.
lyman b on Jul 27, 2017
When I don't want to change out my table saw blade I found this convenient and accurate.

Wanted an alternative method to making smooth accurate dados without using my table saw.
jason m on Oct 9, 2016
a great combination for straight dado cuts. Much quicker than setting up the table saw with dado blades.
David L on Jul 26, 2016
I tried cutting dados with a makeshift jig.....didn't do a great job....created a flimsy slot....tried another one...same result....saw this on you tube and's in a track, it can't I bought it....I'll let you know how things work out

Looked like a good way to create shelf dadoes for 3/4" boards, but didn't fit my Craftsman router.
Larry N on May 8, 2015
Attracted to what appears to be good control of the cut, and allows reasonable selection of dado widths.

Is this jig compatible with triton 3hp router?
sam s on Feb 24, 2019
BEST ANSWER: Don’t know about Triton router. It didn’t fit my Marita or Craftsman. Haven’t gotten around to trying to modify base of router to make it fit. Clamp is wonderful and I use it all the time.
Can I buy the jig without the clamp? I already have several
Joe D on Apr 8, 2018
BEST ANSWER: Hi Joe. The jig fits a slot in the clamp. So yes but I wouldn’t recommend it. However, I can’t really recommend the jig either. I found it to be unreliable
Mounting holes do not match Sears Routers What is the fix???
Istvan on Dec 26, 2015
BEST ANSWER: Hello, you will have to drill your own mounting holes. I took off the base plate from my craftsman router and centered the center holes as best I could then drilled new holes using router base plate as a guide. Then I used a 3/8 countersink bit and drilled slowly until screws were just below the surface.
Will it fit craftsman model 315.175040 routers ?
Thomas L on Mar 20, 2019
BEST ANSWER: Not sure. The base has 3 screw attachment points tat are 120 degrees apart. If your router base has 3 threaded holes in that pattern then it should fit. I have a Bosch router. This is an awesome tool.
Does it fit with Makita DRT50ZJX2 18V Li-Ion Cordless Brushless Laminate Trimmer Router ?
Masood A on Aug 17, 2018
BEST ANSWER: You would need to drill holes in the jig to use that size router
I have to do a 2" dado will this adjust to that?
Mullet6 on Apr 24, 2018
BEST ANSWER: Yes. If you are using a 3/4" router bit, you would need to loosen the two lock bolts and move the router over twice after the initial cut to reach the 2" width.
Will this work with a Bora clamp?
Robert G on Apr 14, 2016
BEST ANSWER: Compatibility is universal, although additional holes in base may have to be drilled to accept the odd router (non-standard) .
What size bit to use for 3/4 plywood?
Pat J on Jun 15, 2015
BEST ANSWER: We offer some undersized router bits for plywood. The number for the 3/4" plywood is 90264 it measures 23/32"
I already have an undersized 7/32 bit. Can I use this jig just to route channels at precise widths?
