Canvas socket studs snap into canvas sockets. Both are secured to canvas fabric by intergral prongs which pierce the fabric, and are then folded over a backplate or washer on the other side.
Use to attach one piece of canvas to another - such as a door in a canvas dodger. Or closing a seam between removable canvas panels.
