A rope wrench comprising or including a base plate having a lever arm at one end and a lever handle opposite the lever arm, a pair of bollards at the lever arm end for receiving therebetween an anchored climbing rope, and a gate spaced from the back plate and pivotable about one of the bollards, thereby permitting mid-rope access to the bollards when open and preventing mid-rope detachment when closed, the arrangement being such that when the gate is closed and the lever arm is rotated by the handle about the major axis of one of the bollards they collectively cause the rope to assume a serpentine shape to shorten the effective length of the main rope and assist ascent by the climber or to impart friction to the rope when descending whereby to permit controlled descent.
