Corner Clamp for Woodworking, 90 Degree Corner Clamp, 4 Pack 5.5"x 5.5" Aluminum Alloy Right Angle Woodworking Tools, Positioning Squares for Picture Frame, Box, Cabinets, Drawers

Perfectly square. Solid. Looks as good as they seem in the pics. Good purchase.

I'm using these with some hand clamps to make certain wood joints are square. They've worked perfectly for what I needed them for. I initially wanted the longer length to clamp over the 6inch outside corner. I've been able to clamp on the inside of the corner for most things but the farther away you clamp from the corner the easier it is to see out-of-square and the more leverage you have with the clamp to move things to square. They are very strong. I wouldn't expect to ever bend them. Since I'm using them to square 2x4 and 2x6 inch boards laying flat I cannot use the spanning pieces but the hand squeeze clamps work great.

Purchased these to use in my woodworking shop. They are very well constructed and surprisingly accurate. I have used these to build drawers units with excellent results. The size is ideal for most projects and easy to work with. Highly recommend.

Excellent product. Helped me square my large 3d printer frame. Great for squaring 2020,2040,3030,and 4040 extrusion.

I got this Clamp set for working with aluminum extrusions building 3D printer frames and tables and carts and such. It really clamps the work securely. It is light weight and the case to store it in is pretty nice. I don't notice any weak points or anything. I think it will be durable.
