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 recommend ascending with gloves on except in cold conditions).
In the ID column, I used a red background for cast frame ascenders, green for extruded frame ascenders, and blue for stamped frame ascenders.
