Rotodraper ® Pivot Arms

Rotodraper® pivot devices are used for changing the position of curtains on tormentors, side legs, backdrops and cycloramas. The effect is easily accomplished either by turning the curtain itself or by fastening a towline to the curtain pipe and pulling the tow line until the curtain is in the desired position. The pivot device is unique because no implement is required to secure the curtain to its proper position. The Rotodraper® is simply installed and easily manipulated to any angle desired including a full 360° turn

   #28A Rotodraper® with index plate   # 14 Rotodrape®   #06 Rotodraper®

Models 28-A, 17-A, 14-A, and 6-A include an index plate and spring-loaded roller latch which secures the device at 15 degree intervals and helps to prevent accidental rotation.
With the use of a special brake, track-type Rotodrapers® can be secured at any location along the track, helping to prevent accidental movement of the device. Simply by pulling down on the cord, the brake is released and the pivot arm moved. (Obtainable as an option.)
