Rockler Clamp-It® Corner Clamping Jig

Struggling to hold cabinet parts in alignment while driving fasteners can be an exercise in frustration, and if you're using a nail gun, downright dangerous. The Rockler Clamp-It® Corner Clamping Jig eliminates that frustration by providing another set of ''hands'' to hold your parts together. It's used with the enormously popular Clamp-It® (#29190, sold separately) to hold panels at a precise right angle for fastening. Used in sets of four, the jigs are supportive enough to hold an entire case assembly as it is being assembled. The clamps have soft pads to prevent workpiece marring. Mounting holes in the jig allow for attachment to your work surface.


Features:
  • Extra-wide base, high walls and strong Acme threaded clamp screw hold panels securely
  • Thick cushioned pads to prevent marring
  • Durable glass-filled polycarbonate construction
  • Mounting holes allow for attachment to work surface for creating assembly jigs
  • Jig holds panels exactly 3/4'' off the work surface so you can use scrap boards to support other corners if using only one jig at a time
  • Drilling of 3/8" holes may be required in older Clamp-Its for use with this product.

Square corners are easy with this jig. I've used this jig on several projects and it has made it so much easier. My only complaint is the black 90 degree pieces do not come with the jig. Without them the jig is almost useless, but they have to be bought separately.

Great addition to my shop.
The corner clamping jig helped me assemble a cabinet base so much easier. It was like having an extra pair of hands and it resulted in an accurate 90 degree corner.

That extra pair of hands you need
great for building cabinets, hold the parts in place while you attach the panels makes an normally y awkward job a simple single person operation. Look to be strong enough to last a long time given how much I'll use them.

Because I love my husband and I want him to be happy on his birthday and in his man cave where he is joyful creating, repurposing, and doing something on the honey do list. "He taught me, if you buy right the first time it only hurts once". That is why I buy at "Rockler".

Would it be ideal to have 4 of these while building cabinets or only having two will do just fine?
Trevor O on Sep 15, 2015
BEST ANSWER: If you are building larger cabinets, four might come in very handy
Can item 69954 be used with this item? I ordered 2 of these plus item 69954. Kinda ridiculous this item doesn't include the black plastic squares are ready
Trevor O on Sep 15, 2015

Can the Rockler Adjustable Clamp-It Assembly Square (Item #33586) be used with this? Or just the fixed 90º Assembly Square?
Lane B on May 7, 2016
BEST ANSWER: This was designed for the fixed Clamp-it
Will the 58918 hold 3/4 inch plywood plus the 29190?
Thomas C on Sep 3, 2015
BEST ANSWER: Yes, it will hold up to 1" plywood plus the Rockler Clamp-It® Assembly Square (Item #: 29190)
Are there any similar products that would work for assembling carcasses built from 2x4's?
mcilroy50 on Jan 22, 2016
BEST ANSWER: You can build your own narrower versions of the 29190 square add-on to clamp thicker materials if you need a higher lip on the backside. Otherwise you can go up to just shy of 3 inches without the 29190 square inserts. With the 29190's in place the maximum width is just shy of 1 inch. Not sure why Lyman L said small wood. So the answer is maybe, it you are talking about the 1.5" dimensional side of the 2x4, but not the 3.5" dimensional side.
What would be the smallest box you could make before the clamps would bump into each other? I'm thinking it would be around 18"?
groundhog on Feb 18, 2016
BEST ANSWER: Looks like about 8" X10.25" insde clearence. These clamps are excellent for aligning larger pieces that are to assembled with screws but are not good for asembling mitered boxes which require pressure from both directions. With that said very helpful in assebling cabinets etc.
I often build large wooden boxes with box joints. Will these work well to glue them square? Thanks!
carl c on Oct 5, 2015
BEST ANSWER: Hi Carl. These clamp-it jigs are very heavy duty and work great. You must also purchase the clamp-it square (below) to go with each jig. You need at least 2 of each to be effective. I purchased 4 of each to give more versitality. They are very pricey and I regretted purchasing them at first because of that, but they have proven to be very helpful when aligning large projects. I also purchased 2 sets of the mini clamp-it assembly sets.

Would these work with Kreg pocket hole assembly?
Ted K on Oct 28, 2015
BEST ANSWER: They work really great. It is like having an extra set of hands. Highly recommended for any shop!
What is the maximum thickness of wood it works with?
Joseph D on Oct 28, 2018
BEST ANSWER: Up to an inch. Works really great on 3/4 inch just like they say. A second pair of hands. I have 4 units. Great tool.
Under the heading of "what's included", it states 1inch screws to attach Clamp-it (28120 screws not included). Are they included or not included?
George E on Jan 19, 2016
BEST ANSWER: The screws are included.
Part number 28120 does not appear to exist.
Part number 29190 in the current listing, which it says is is not included, is the black right-angle assembly square you see in the picture used with the corner clamping jig in question.
I bought two of these corner jig clamps and they arrived with out the black angle pieces shown in the photos. Are they not included? The clamps appear to be useless without them.
Larry Q on Feb 3, 2018
BEST ANSWER: It's used with the Clamp-It® #29190, sold separately.
Would I be able to use these with Woodpecker brand clamping squares? It would make setup time much faster than using separate clamps.
Ted K on Oct 17, 2016
BEST ANSWER: I bought two of these clamps and they have been a great help in many different projects. They certainly made the job much easier. They are easy to use.
Will this work with your mini squares?
