TRU-ROLL TRACK CORD & CABLE:
The following types of operating line are used for Tru-Roll track assemblies.
3/8 inch sash cord or bell cord are generally used for hand operation. Wire-core bell cord, which is less suseptable to streaching, is perfered.
Nylon coated wire ropes offers additional strength, less streach and are used for Drag Lines and Truss Track operation. Drag lines are normally made from 3/32” wire rope with an 1/8” nylon coating. Heavier nylon coated cables are typically used for Truss Tracks.
Lift Curtains may be rigged with 1/8” to 1/4” sash cord or wire rope with selection dependent on the size and weight of the curtain.
