Cable Ascender

This page is a chapter in 'BASE Wiki Other Gear'

Glen Martin Wire Rope Grabs are precision-crafted for vertical fall arrest protection. The cable grab device is a cam activated fall arrester which slides freely up and down a 3/8" (9mm) steel wire cable. Works great on both galvanized and stainless steel cables.

The cable grab is connected to the chest attachment points on the climbing harness via the included carabiner.

Meets all OSHA and ANSI regulations for vertical lifelines.

These Canadian cable ascenders are the TOP PICK! Small sleek, easy to load; locks in with carabiner. No funky pins or chains to tangle with! CABLE GRABS Cable Ascenders are used on vertical belay systems. This is a removable device that automatically travels along a 3/8 in. steel cable permitting a climber to use both hands while ascending or descending a vertical belay cable, climbing pole or cable protected ladders. The cable Ascender grab is made of stainless steel for protection against rust and corrosion. For use in all conditions. In some situations it may require the use of a load limiting device. An Auto-Lock Steel Carabiner is included.


A cable grab safety device which releasably attaches a workman's safety belt or harness lanyard to a vertically extending safety steel cable or the like. The device includes a primary frame assembly constructed of an elongated U-shaped bracket having a pair of spaced apart parallel side plates which is adapted to fit around the cable. A secondary frame assembly also comprised of a pair of side plates is adapted to fit within the U-shaped bracket after the cable is inserted. The secondary frame assembly carries a brake mechanism in the form of a pulley mounted in an elongated slot so as to be movable toward or away from the cable and a lever adapted to be attached to a worker's lanyard for moving the pulley so as to engage the cable in the event of a fall. This unit follows along with the climber and locks into place if a fall occurs.

I have also found these:

Safewaze fall protection Rope Grabs for synthetic rope lifelines qualify as OSHA-compliant energy absorbing components of a fall arrest system. When using a vertical cable rope grab for wire lifelines, an energy absorbing lanyard must be used. When using any rope grab, freefall distance must never exceed 6'.The best way to ensure a freefall of 6' or less is to use a 2' or 3' long lanyard.>>

Safewaze fall protection is a proven performer in rope grabs and cable grabs. Years of research and development have resulted in simple designs and reliable lightweight products. In the event of a fall or slip, they lock onto the rope or cable, arresting the fall immediately. The automatic grabs follow the worker without assistance. >>

> >

Applications: Small, lightweight rope-grabbing devices ride a vertical lifeline and automatically lock in place if a fall occurs. Rope grabs and cable grabs prevent workers from falling when ascending or descending. The range includes models for horizontal and vertical applications. They are particularly useful on sloping roofs where retractable lifelines may react too slowly.
