The look and feel of this clamps are consistent with the high quality we're used to from the rest of Relitec R's lineup. Anyone who has struggled to get a regular-sized square into an irregularly under-sized corner will appreciate the value of these little tools immediately.

It keeps material square while being glued and while attaching stretchers.

These are reasonably accurate for basic woodworking. They're essential when building anything with 90 degree corners. They're very rigid and durable, thicker and wider, suitable for more workpieces.
