These are double heavy duty hangers for picture frames and paintings. They are far stronger than the eyelet style hanger, and mount with four screws. The package includes 20 hangers – two for each frame. Screws are included. Enough hangers to do 10 paintings! Check out the various size BRAIDED PICTURE WIRES on the TOOLS & GADGETS pages for use with these hangers.
A two-screw version is available here.
