Overview
A set of four 5.5 inch Corner brand clamps sold with a storage box, designed to hold two pieces at a 90 degree angle for picture frames, box joints and other mitered corners.
Corner clamps solve a problem standard bar clamps do not: squaring two edges at a right angle while glue sets. Selling four in a box lets a builder clamp multiple corners of the same frame or box at once rather than one joint at a time.
- 5.5 inch clamp size
- 4 pack with storage box

Who it's for
Fits picture framers, box builders and woodworkers assembling mitered corners who need several clamps working together. Not useful for straight edge gluing or wide panel clamping, which need bar or pipe clamps instead.
Strengths and trade-offs
Drawn from this product's published specifications.
- Holds corners square while glue cures
- Four clamps let you finish a whole frame at once
- Comes with a box for storage
- Only useful for right angle joints
- Not a substitute for bar or pipe clamps
- No description text on clamping force
Performance notes
Each clamp holds two workpieces at a fixed right angle, so glue can cure without the corner sliding out of square. Having four on hand means every corner of a frame or box can be clamped at the same time instead of waiting on one joint before starting the next.
