350 Curvit-Sure® Stage Curtain Track System

 

 

Curvit-Sure® 350 is a double-sectioned curved stage curtain track designed for medium weight curtains on bi-parting lengths of up to 60' (layout dependent). All curves are factory formed with a minimum radius of 6' (layout dependent). The operating cord is routed through a trough and idler system and does not come into contact with any carriers except the masters. The broadsides at each end have 1-1/4" cutaway area to allow for insertion or removal of single carriers. Anti-friction tape and nylon spacers applied at critical areas reduce noise and friction. Manually operated cord-drawn curved tracks require more pulling effort than straight tracks. Therefore, curved tracks should be motorized whenever possible.

Curvit-Sure® tracks cannot be used in reverse curve applications.
