Single Brake Bar Descenders

These descenders have one and only one brake bar that swings open for rigging. I exclude the use of a "normal" brake bar on a single carabiner, putting this on the Carabiner Brake Bar Methods page, but I include unusual brake bars such as the Charlet Moser, PFH Pitt Stop and Wagner Brake Bar here. Descenders with multiple brake bars that swings open are covered on the J-frame Racks and O-frame & U-frame Racks pages or, in a strange case, the Miscellaneous Descenders (for the J-Bar).

Note that it is a "Brake Bar," not a "Break Bar." Think about it.
