Intended for rescue operations, The Petzl I'D L Self-Braking Descender is the larger version of one of the world's premier descender devices. It features an anti-panic system that, whenever the user pulls the handle too hard, it stops the fall. One of the main reasons so many of our customers trust the I'D L is because of its anti-error design. This feature greatly reduces the risk of a mishap due to incorrect installation of the device's rope. Another big plus with Petzl is that installation is incredibly simplified and can be performed quickly. The descender's multi-function handle is very easy to use, allowing workers to position without the need for tie off at a work station. Using the ergonomic handle, you not only descent, but make short rope ascents. If a worker experiences an involuntary action, he can effortlessly snap the handle back into the lock position. Made of solid aluminum alloy, the I'D L Self-Braking Descender is both lightweight and strong and is ideal for our customers in tower climbing or any other site where your workers perform rope access work.
