Cleco Side Clamps Fasteners Edge End Grips 1" x 20mm Opening Pack of 2

There are 2 different opening sizes for Clecos, the ones with a brass collar open 20mm and the ones with a copper collar open 15mm. I thought I was buying the 20mm opening clamps as advertised but I was sent the 15mm opening clamps. I kept them because they will come in handy one day but I was not able to use them fro the purpose for which I bought them as they did not open enough.

Compact, strong, well engineered they can hold all sorts of sheet together from templates to actual panels whilst you arrange more permanent fixings with your two remaining hands.
