Abstract: A wall-climbing accessory adapted for mounting onto a wall structure is described. The wall-climbing accessory comprises a resilient body that is flexible. The resilient body comprises an exterior surface and an edge. The exterior surface is configured to provide an engagement point capable of supporting a climber of the wall structure, whereby a climber may scale a wall structure by using the wall-climbing accessory. The edge is configured to substantially engage the wall structure such that, when affixed, the resilient body and edge impart a torsion force to the wall structure such that a flexible, friction fit is formed between the wall-climbing accessory and the wall structure. The wall-climbing accessory use only one primary fastener to attach to the wall structure and thus is less prone to rotation than prior art climbing holds. Furthermore, the resilient body is flexible and lighter when compared to prior art climbing holds.
