Model 421 Curtain Track

ADC Model 421 curtain track system is identical to ADC Model 420 curtain track except that it is ENTIRELY STRAIGHT IN LAYOUT and No. 1403-B Live-End Pulley is used instead of No. 1403.
ADC 420 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 too heavy for 140 series curtain track systems used on stages, TV studios and gym divider installations.

When ordering, advise whether the track is to be ceiling-mounted, suspended or wall mounted.

Also available with a black finish at additional cost (520).



Model 421 Curtain Track

Manually-operated cord-drawn curved curtain tracks require more effort to operate than straight curtain tracks. Therefore, on long track runs motorization should be considered.
