The #1 Ascender is intended for climbing ropes and pack hauling by mountain climbers and cavers. It is not intended for litter raising or the support of more than one person for self belay. For rescue and litter raising we recommend the #3, #3S, #4, and #4S Ascenders.

Gibbs Ascenders are designed not to slip. They hold well on iced and muddy ropes. Their simple, durable construction makes them almost fool proof. They are easy to assemble on the rope yet will not come off unexpectedly. They can be rigged in all the standard methods for mechanical prussiks.
