<p>A belay device operable for guide mode belaying is disclosed. The belay device comprises a body (10) that includes a rope slot (22) through which a bight of rope (50) can pass, a guide-mode anchor (12), and a release formation (30), in which the guide-mode anchor is pivotally connected to the body, the device being operative to cause frictional locking of a working length (56) of the rope in a condition of loading on the rope corresponding to that which occurs in the event of a fall of a belayed climber. When the rope is locked, the body (10) pivots with respect to the guide-mode anchor (12) to increase mechanical advantage of the release formation (30) with respect to load applied by the working length (56) of the rope on the body (10).</p> |
