Rocker Arm Ascenders

These are ascenders where the rope passes under a rocker arm and above an anvil. Tension on the standing line rotates the rocker by raising the standing line end of the rocker, pinching the trailing line between the other end of the rocker and the anvil. The load is supported by the ascender shell through the rocker fulcrum. Most of these are inefficient because of considerable lost motion as the ascender rotates under load.

Many Rocker Arm Rope Grabs can be used as ascenders and could have been listed on this page instead. The choice to call them rope grabs instead of ascenders may be arbitrary, but I usually followed how a device was marketed to me when the choice wasn't clear.
