Longer rigid stem design of the Super Belay Gadget II maintains a fixed distance from your locking carabiner and allows choice of clip-in point and rigging "V" grooves or "U" slots for your preferred amount of friction and braking power. Because of the "fixed distance design" the SBG is smooth and predictable - whether arresting a fall or keeping your composure while backing over the edge for some big air. Rig for low, medium, high or super-max friction with ropes from 8-11 mm. Order up a JAKE SCREWGATE biner to go with your SBG for the ulimate performance combo.
