Handled Eccentric Cam Ascenders

This section includes mechanical ascenders consisting of a shell or frame and an eccentric cam assembly attached to the shell/frame at a single pivot point. The shell/frame is open on one side to allow admittance of the standing rope. The shell/frame below the cam is enlarged to provide a handle. No sling attachment points are provided on the cam.

These ascenders are generally larger and heavier than the handleless eccentric cam ascenders; conversely, they are easier to manipulate, particularly with gloved hands. I don't normally wear gloves ahile ascending (except in cold conditions), but many people prefer to do so.

In the ID column, I used a red background for cast frame ascenders, green for milled and/or extruded frame ascenders, and blue for stamped frame ascenders. Magenta indicates a two-rope ascender.
