From our bench

Holding a corner square with one hand while driving a screw with the other never ends the way you wanted. These blocks clamp both boards at once, carry a scale on every face, and the anodized body will not bruise a show side.

Square without a hand

Each block takes a board on both legs and holds the inside corner at a right angle while you glue, screw, or drill. Four of them set up a drawer box or a picture frame before the glue starts to grab.

Thick stock fits

The long extension bolts reach over stock about as thick as a stair tread, and the positioning blocks slide to clear a rabbet or a dado. Knobs tighten by hand, so no wrench joins the pile on the bench.

Scales on the faces

A laser engraved scale runs along the faces in both metric and inches, so a repeat offset can be set off the block itself instead of chasing a tape measure back and forth across the bench.

What the box holds

Four clamps, the positioning blocks, the long bolts, the knobs, and the washers come in a fitted box that stacks on a shelf. Every piece goes back into the hole it came out of when the glue is dry.
