About: ISC - Shear Reduction Block Pulley

The RP029 Shear Reduction Pulley is made from Stainless Steel and fitted with a top bollard attachment point. The top bollard has been designed to be compatible with a standard 10mm (approx 3/8”) long opening Maillon Rapide.

The wheel of this pulley does not rotate, giving maximum friction. The increased friction makes this pulley ideal for increased control when used in lowering applications such as top roping in Climbing Walls/Gyms and Ropes Courses.

The top bobbin of the RP029 is designed to be compatible with the MRGOZ10.0EN long opening Maillon Rapide (also CE Approved) for applications where the use of a screw-link is important. CE Approved to the PPE Directive.

Each Pulley is serial marked for ease of traceability.
