The machined cooling fins on Trango's Pyramid work both to keep it cool and to make it less droppable, and the pivoting center pin lets you flip it over to customize the feed of your ropes without effecting its stopping power. Rappeling is always controlled and jerk-free and the flat rope path virtually eliminates kinks. The elongated slot for the center pin makes it easy to rig the Pyramid with stiff or fat ropes and the burly retaining cable will last as long as you own it.
