New and improved, our SBGII is the smoothest & most versatile belay device available! Based on a design by Greg Lowe, the all newand improved SBGII is the smoothest and most versatile device available. By incorporating a rigid stem on this device,climbers can go from full lock-off to whipping rope out in a single, smooth action, no more binding up as the device tries to free itself! And the amount of friction can be completelyadjusted to suit your particular need. Does your climber outweigh you? Are you using skinny ropes? Then set up the brake line through the V-Slots! Clipping in short (into the oblong hole in the center of the stem) adds even more braking power. Climbing with fat ropes, a skinny partner or on low-angle slabs? Then belay off the U-Grooves for less friction and clip into the bottom hole of the SBGII! And if you've ever rapped on a single 8mm or 9mm ropes with a traditional belay device, you know what a fast and loose ride that can be! With the SBGII, wrap that skinny cord around the rigid stem and rappel figure-8 style for the ultimate in control and safety.
