The Micro Hauler is a tiny but extremely strong and efficient version of the Rescue Hauler. It comes in either single or double pulley versions. The cam is guaranteed for life. The pin must be removed to allow the rope to be removed or inserted. When the pin is in place it allows the cam to be opened just far enough to allow travel in both directions but it can not come out accidentally. Black andoized alumimum sideplates, two 1 1/4″ aluminum sheaves, bushing and aluminum axle. MBS: 7,000lbf Length: 6” Sheave Diameter: 1”
