Description
The DUPLEX is a compact and lightweight double pulley device with a pair of sheaves arranged in parallel.
The shape of its side plates is specially designed for use with a Prusik friction knot in progress capture systems, simplifying lifting loads and setting up polyspasts.
The pulley is mounted on a steel ball bearing to maximize working efficiency. High precision of manufacturing on CNC machines ensures significant minimization of friction losses.
