This is a set of two nylon guides for 1/2 in. square header and threshold bolts found in some commercial aluminum or steel doors. This guide helps guide the rod through the top or bottom of the door and into a corresponding hole in the header or threshold. The two guides are nylon with a single mounting hole.
