PMI/SMC AscendersPMI is a distributor for HeighTec, one of the leading name names in rope grabs
Gibbs AscendersThese ascenders use a ridged cam and a solid shell to grip the rope. Spring loaded models will support their own weight when there is no load on the cam. Stainless steel and the #3 models exceed ANSI standards for rescue and industrial applications. The #3, #2SS, #4 and #4SS all feature a curved cam/shell interface to increase the holding ability on a rope.
