Why This Tool Is Worth It

Assembling a cabinet or a box by yourself is the moment most woodworkers wish they had a second set of hands. Panels want to slide, corners want to rack out of square, and you end up holding everything with your knee while trying to drive a screw. This jig solves that by clamping both panels into a fixed 90 degree corner and staying put, so your hands are free for the drill, the brad nailer, or the glue.

The design is what makes it hold up under real assembly. Two wide bases bolt to a Clamp It Assembly Square that sets the angle at exactly 90 degrees, and those bases have high walls and strong threaded clamp screws to lock panels down tight. Quick release buttons let you slide the clamp screw in and out without spinning a knob 20 turns, which is a big deal when you are working through a stack of cabinet parts. Cushioned pads keep the clamp screws from denting your workpiece and non slip pads stop the jig itself from wandering across the bench.

The details show this was built for production as much as one off projects. The jig holds panels exactly 3/4 in off the worksurface, so if you only use one or two you can shim the other corners with scrap and keep everything level. Mounting holes let you screw them down to a bench with #8 screws and build a permanent assembly station, and the offset matches the original Clamp It Corner Clamping Jigs so you can mix old and new. In sets of four they will hold an entire cabinet upright while you assemble it, and with glass reinforced ABS construction plus capacity for stock up to 1 1/2 in thick, they handle plywood, hardwood, and thicker case parts alike.

Features

• Provides another set of hands to hold case parts together at a right angle for fastening

• In sets of four, the jigs are supportive enough to hold an entire cabinet or case upright as it is being assembled

• Jig consists of two bases bolted to a Clamp It Assembly Square, which positions the bases at 90 degrees

• Wide, stable bases have high walls and strong threaded clamp screws to hold panels securely

• Clamps have quick release buttons for making fast adjustments without threading or unthreading

• Easy to grip 4 Star Knobs

• Bases accommodate workpieces up to 1 1/2 in thick

• Cushioned clamp pads prevent marring

• Non slip pads keep clamping jigs from shifting during use

• Jig holds panels exactly 3/4 in off the worksurface, so you can use scrap boards to support the other corners if using only one or two jigs at a time

• Height offset matches the original Clamp It Corner Clamping Jigs, so they can be used together

• Mounting holes let you attach Corner Clamping Jigs to a worksurface with #8 screws, to create assembly stations

• Durable glass reinforced ABS construction

Who This Is Best For

This is made for the woodworking shop that builds boxes, and that covers a lot of ground. Cabinets, drawer boxes, bookcases, shop storage, toy boxes, nightstands, and built ins all come down to holding panels square while you fasten them. If you work alone in a garage shop with no one to hold the other side, this is the accessory that most changes how assembly day goes.

It is especially valuable for anyone selling what they build. Cabinet makers and furniture builders assembling multiple identical carcasses benefit from mounting these to a bench and turning it into a repeatable assembly station, because square and consistent parts mean doors and drawers fit without fighting. Anyone who has pulled a case out of clamps only to find it racked will understand the appeal immediately.

Where it is less useful is small scale joinery and non 90 degree work. This is a case and cabinet tool, so angled frames, miters, and tiny boxes are better handled with other clamping methods. For right angle case assembly, it is hard to beat at $33.99.
