Handleless Eccentric Cam Ascenders
Chest 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. No sling attachment points are provided on the cam. No handle is provided.

I split the Handleless Eccentric Cam Ascenders into these three groups:

Chest ascenders are specialized for people who prefer to climb with the Frog System, or are required to do so because of where they live. Almost all chest ascenders are left-handed, reflecting the bigoted views that normal people are right-handed and right-handed froggers need left-handed chest ascenders. Proverti is one current manufacturer that does not express those views with their product line.

In the ID column and chart, I use a red background for hand ascenders, green for chest ascenders, and blue for emergency ascenders.
