We would like to introduce you to Golfire’s Patent Pending “G Zero” Auto Locking Ascender/Descender for Firefighter Escape. The G-Zero weighs approximately 7.4 ounces. An auto-locking feature adds the security and confidence for a hands free exit of the building. Built to allow for easy horizontal movement to your point of egress. Your left hand controls your descent while your right hand releases the rope. Let go and you STOP! The low profile shape and size will fit in any bag and makes a great addition to any existing bailout system! Use with rope or webbing!
