HAAS Ascent System
09/03/13
Ever wish you could climb with two foot ascenders?
The new HAAS system (developed by Michael Frankhauser of Ohio) features a fully integrated knee ascender that captures all of the advancement made by your other foot. It gives the climber an easier and faster way to ascend and can be used with double rope, SRT, Rope Wrench, Hitchhiker, or whatever.
Basic Concept: Until now, only one foot ascender could be used. The HAAS deals with this by moving the operational range of the "other foot" above the foot with the traditional foot ascender. The key is the patent pending integrated bungee design which runs the length of the lower tether giving it full operational range of pull.
