Strap clamps are the go-to clamps for mitered frames, mitered boxes and many other tricky clamping situations. But juggling all the moving parts without having one of the corners slip out of place or off the table can be difficult. Our design solves the problem by anchoring the clamping head to a T-track, or to one of our T-track tables. This ensures that the clamping mechanism is always in the same place and doesnt slide off the bench. One of the plastic corner brackets also has a guide that slides in the T-track, letting you use the track and the edges of the table to check for square. The improved stability is a welcome relief when clamping multiple frames, since things stays largely in the same position when you switch frames. Insert the new frame, pull on the strap to snug up the corners, and give the ratchet a few cranks to squeeze the gaps out of the miters.
