Compare a corner vise, a band clamp and a frame joiner
A clamp aligns the molding while you work on a joint. A joiner drives the specified fastener. Choose them around the section and perimeter of the frame you are assembling.
Match the clamp to the frame perimeter
A band clamp can bring several corners together in one setup. Check the strap length and the usable perimeter around the blocks. Compare corner shapes and where the blocks will touch a decorative face.
Check the jaw opening for a single joint
A corner vise is useful when you want to work on one pair of miters. Check that the profile sits flat in both jaws and that the faces you need to align remain visible while tightening.
Match the joining hardware
For a V-nailer, check the exact fastener profile, feed style and the molding material supported by the maker. A strip, cartridge and loose wedge can require different holders even when their lengths appear similar.
