By incorporating a rigid stem on this device, climbers go from full lock-off to whippingout rope in a single, smooth action�no more binding up as the devicetries to free itself. The amount of friction can be completely adjustedto suit your particular need. Does your climber outweigh you? Are youusing 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) addseven more braking power. Climbing with fat ropes, a skinny partner or on low-angle slabs? Then belay off the U-Grooves and clipinto the bottom hole of the SBGII for less friction. If you�ve everrapped on a single 8mm or 9mm rope with other belay devices, you knowwhat a fast and loose ride that can be! With the SBGII, wrap thatskinny cord around the rigid stem and rappel, figure-8 style, for theultimate in control and safety. |
