Gibbs Ascenders

Used for years by cavers, Gibbs Ascenders provide excellent performance under the most adverse conditions, gripping muddy and icy ropes. They are also used by many rescue teams for ratchets in haul systems and in other rope-grab applications, where a mechanical ascender provides greater efficiency. The sport models are intended for ascending rope and work well for pack-hauling systems for climbers and cavers. The rescue models have a heavier shell and larger diameter pin for greater strength when used in a litter-hauling system. On all models, the bottom of the shell has been modified to provide a curved interface with the rope for greater strength. With the spring-loaded models, the spring prevents the ascender from sliding down the rope when the cam is not loaded. All models fit rope from 11–13 mm (7/16 –1/2 in).   Note: The breaking strength applies to the unit. The actual Gibbs/rope performance will vary depending on the type, brand, and condition of the rope.
