مشبك إطار رباعي الزوايا قابل للتعديل من Infinity Tools

I was worried my 26x30 frame would be too big for this thing, but it fit with room to spare. The adjustable corners tighten down evenly, so I didn't have to fight the joints sliding around while gluing. Best ten bucks I've spent on the shop in a while.

The corner clamp held my mitered joints perfectly square on a 24x30 mirror frame, no gaps at all. The adjustable jaws tightened evenly without crushing the walnut, and I didn't have to fiddle with four separate clamps. Glue-up went from stressful to actually kind of relaxing.

Clamping a 26x30 frame used to mean four separate clamps sliding all over the place. This one holds all four corners at once and keeps the miters tight while the glue sets, and the adjustable arms actually stay where I put them.
