Milescraft 4010 4" ClampSquares - 90 Degree Corner Clamp, Positioning/Assembly Squares for Small Projects Jewelry Boxes, Boxes, Etc , Black

I've been building some fiberglass ice boxes, and these are very handy for square.

Do a lot of boxes. These are accurate and great to keep sides square.

They do what they are supposed to. Worked well on my project. Useful with the Milescraft clamps as well. Price of MC products for what you get makes them a great value. No need to go for the higher priced items in most cases.

Built two cabinets so far, very helpful during assembly. Actually like having an extra set of hands. Good quality and accurate. I will be getting more.

Bought to add to others I own.

I use it all the time

My engineers square says they are 90 degrees. Ckd. some square. corners on book cases and fit tight. Both inside and outside square. Cked. them against my R brand and can't find any difference. Would buy again. As always caveat emptor.

Work well. Easy to use and durable.

Excelente tamanho e praticidade de uso.

Making drawers I found these ideal when space was limited. Would have been perfect if came with small clamps, why do I always need more clamps.

Fácil uso muy útil para trabajos manuales

Their ok

It works well for its intended purpose and for plastic is quite heavily reinforced, though you can flex it out of square with enough pressure. Grooves for the bars are wide enough to accommodate Irwin and Jorgensen one hand squeeze clamps. It does work with their fence clamps though it can be a faff. It will clamps something at 90 but it will not pull something into 90 so it's not really suitable for heavy duty tasks. Works very well as a reference block for heavy duty stuff. Plastic is fairly resistant to glue and even Stixall just needed some isopropyl to come off cleanly.
