Keyhole rivet hangers are designed for use on rivets or hangerless bolts and are stronger and more durable than traditional cable rivet hangers. The beefy 0.090”-thick stainless steel hangers inspire confidence and make it possible to utilize the full strength of a rivet or bolt. Compared to cable rivet hangers, keyhole hangers are shorter in height, enabling a climber to gain maximum reach from a rivet or bolt. Both the 3/8” and 5/16” hangers are designed for added security such that once clipped with a carabiner, the hangers cannot come off of a rivet or bolt until the carabiner is unclipped from the hanger.
