The CMC 3D locking-bar descender delivers the ultimate in safety, control and performance, in one compact and lightweight brake bar rack style device designed for rope rescue. The 3D features two sliding bars for optimum friction control and efficiency. The horn design works well with 13mm rope and smaller, making it easy to add or subtract friction as needed throughout the evolution. The frame dimensions allow for larger rescue-sized carabiners to be used without any contact or friction with the rope. The descender can be loaded or unloaded while connected to your harness for rappelling or to an anchor for one- or two-person rescue lowers.
