3M DBI SALA® Wood pole fall restricting device was developed with help from real pole climbers and features effortless adjustment and "cynches" around the pole during a "cut out." It meets CSA Z259.14 standards for Type A and AB (dry, wet and icy poles) and ASTM F887. The wood pole fall restricting device allows you to easily hitch hike poles (move or jump the strap upwards) with a hand position that's comfortable. It also moves past obstacles without difficulty. Exterior straps can easily be swapped out in the field depending on pole size, eliminating the need for multiple systems.
