Pulley/Rack combo

[ssurveyor]

I have been experimenting with this device I made, which is essentially a modified ANSI size 80 chain, with stainless steel headstock with integral hitch cord and hitch climber pulley. The collapsing rack has rollers where the climbing line enters and exists the rack. The rack adds friction below the hitch so that it can be used SRT and on a doubled rope.

Here is a youtube demo made by an arborist online friend. Thanks Tony!
