Best With quick release: Powertec Corner Clamp kit

Buy on Amazon

Next on the list, we've got yet another kit that manages to win our hearts. It's the powertec corner clamp kit and it's widely considered as kit that has the most suitable features. This kit is designed to help you independently tighten all four corners to produce solid, perfectly squared frames without damaging your material. It is extremely useful helping to align miter joints on a large frame with less than perfect joinery. The adjustment knobs are good, but are relatively small in diameter, so this limits the amount of force you can apply to the joints. The additional connector bars offer the ability to frame larger pieces with the sign backing inserted as well.

This jig is pretty darn good and simple. It is great for large frames. The clamp is a little bit fiddly to adjust, but once adjusted, it holds the frame together very well.

Why We Like This:

Precise and accurate at joining adjacent corners
Clamps all styles of picture frames up to 45-12 max
Tightening all four corners independently for dedicated pressure
