Compare your clamp’s mounting area with the dimensions shown below. Compatibility depends on the specific clamp model.
Fit. Position. Clamp.
A straightforward setup that lets you switch from standard clamping to supported corner assembly.
-
Open your compatible clamp. Allow enough room for the adapters and workpieces.
-
Fit the adapters. Seat them securely on the matching clamp mounting points.

Align and tighten. Position your boards, check the joint with a square and apply appropriate clamping pressure.
Keep the Corner Together While You Work.
Boards can shift as you tighten a clamp. The shaped adapter surfaces help support your pieces at a 90° corner, making alignment easier to manage during gluing and assembly.
Spend less effort juggling loose pieces and more attention on how the joint comes together.

Keep these compact adapters ready for your next corner joint. Fit them when needed, then remove them when it is time to return to standard clamping.

Before You Start.
Does this include the clamp?
No. This listing is for the corner adapters only. A compatible clamp is required.
Will these fit every quick-grip clamp?
No. Clamp designs and mounting dimensions vary. Compare your clamp with the adapter measurements shown before purchasing.
Do I still need to check the angle?
Yes. The adapters help position the boards, but you should check squareness and joint alignment before the glue sets. Results also depend on your cuts, setup and clamping pressure.
Can I use the adapters again?
Yes. Remove them after use and store them for your next project. Wipe away glue residue before it hardens and check the adapters for damage before reuse.
