The cam mechanism applies clamping pressure, while pins grip the wood. Steel and brass components support repeated setup work.
The gripping pins contact the wood and may leave marks. Consider the finished surface and test on scrap before working on visible trim. Dry-fit the joint first; a clamp does not correct an inaccurate miter cut.
Use the O'SKOOL PF01 Miter Max corner clamp to hold mitered pieces during assembly. Check the cut and dry-fit the joint before clamping.

The gripping pins contact the wood and may leave marks. Test on scrap and consider the finished surface before clamping visible trim.
