Contour Pulleys

Contour Pulleys are used for the raising and lowering of contour curtains and for other applications where multiple cables must follow a curved or irregular path. Cables can be taken to the end of the curtain or can be run overhead toward the rear of the stage at any point along the contour. Pulleys are equipped with 2-1/2" diameter nylon-tired ball-bearing wheels and should be used only with coated cables. Provisions for up to 20 lines can be furnished for surface-mounting or pipe-mounting.  Note longer assemblies require additional cable or chain support points to prevent mis-performing under load.

Appropriate clews, single and multiple line sheaves are available.

CAUTION: THESE PULLEYS ARE NOT TO BE USED IN HEAVY STAGE RIGGING APPLICATIONS.
