Rope Grabs, Type 1 Lever Cams

Rope Grabs (a.k.a. Fall Arrests) are industrial devices used to protect workers in high places. Their function is to ensure that the worker doesn't perform the big splat when falling from high places; however, they are often used with safety belts that can cause a slower and far less spectacular death by suffocation. This can't be blamed on the rope grab, its the fault of the uninformed user.

My interest in rope grabs is that they are similar to ascenders, and suggest alternate ideas for ascender design. I often discuss these in this context instead of the context of their intended use.

All of the rope grabs on this page have lever cams similar to those found on Type 1 Lever Cam Ascenders. Each of these can be used as an ascender, but some are clearly far to heavy to seriously consider them for that purpose. The steel ones, in particular, are best left for industrial use. I've marked those by a gray background in the weight column. Similarly, some of these are specifically designed for use on steel cable instead of rope, and I've marked those by a gray background in the desciption column.
