Bolt hangers have always been a favorite gear item for the Karabin Climbing Museum. So far over 1200 different hangers are in the museum. Different by shape, bolt hole sizes and color. Also in the museum is 700 historic hangers from routes all over the world. This amazing display was installed into the Phoenix Rock Gym in November 2016. The Hand Drills, Hooks, and Hammers in this display are shown in the "Climbing Gear" section on this website.
