420/422 Tripl-I-Trac® Curtain Track System

 

MODEL 422 TRIPL-I-TRAC® is a heavy-duty I-beam track consisting of four flanges designed to support heavier-than-usual curtains. It is recommended for curtains that are too heavy for 140 series track systems used on stages, TV studios and gym divider installations. Model 420 is used in corded curved applications and utilizes Spindle and Idler brackets (not included CWANA) for guiding the operating cord along curved areas. The track channel can be curved in the field with the use of a bending tool, or at the factory. NOTE: Model 420 cannot be used for cord-operated reverse curved or serpentine layouts. Model 422 is used for walk-along applications where the operator walks the curtain open and closed. No cables, cords, or pulleys are used with this type of system. The track can be curved in the field with the use of a bending tool, or at the factory. When ordering, advise whether the track is to be ceiling-mounted or suspended. Manually operated cord-drawn curved tracks require more effort to operate than straight tracks. Therefore, motorization should be considered especially when sharp curves or long runs are involved.

MODELS 420, 420-R, 421-R, 422 AND 422-R The above models are essentially identical to their counterpart models for the 140 Series described on page 48.
