11 gauge extruded aluminum, mill-finish or anodized black finish [1400-BL]. May be curved on the job to recommended minimum radius of 2' (layout dependent). Center flange prevents tilting of carrier.

Specifications:

RIG-I-FLEX® MODEL 140 RIG-I-FLEX is a versatile I-beam track which has been engineered for both curved (Model 140) and straight (Model 141) cord operated systems as well as for "walk-along" (Model 142) systems. It was designed for medium weight curtains on stages and TV studios and for enclosing areas in industrial plants. Overall track length for cord operated systems should not exceed 60’ for bi-parts or 40' for one-way draws. Model 140 utilizes spindles and idler brackets for guiding the operating cord along the curved areas. The track can be curved on-the-job or at the factory (optional). Manually operated cord-drawn curved tracks require more effort than straight tracks. Therefore, motorized systems should be used, especially where sharp curves are involved.

Model 140-R is identical to Model 140(240) except that No. 4237(BL) Single Carriers and No. 1438(BL) Master Carriers are used instead of No. 4201(BL) and No. 1402(BL).

MODELS 141 AND 141-R Straight layouts only.
Model 141 is identical to Model 140(240) except that it is ENTIRELY STRAIGHT IN LAYOUT and No. 1403-B(BL) Live- End Pulley is used instead of No. 1403. Model 141-R(241-R) is identical to Model 141 except that No. 4237(BL) Single Carriers and No. 1438(BL) Master Carriers are used.

MODELS 142 AND 142-R (242 AND 242-R) Walk-along operation only.
Model 142 is recommended for stage and TV studio cyclorama installations where it is necessary that the operator walk the curtain to its opened and closed positions. The track is curved on-the-job and can be bent to a minimum radius of 2’ (layout dependent). No cord or pulleys are supplied with "walk-along" tracks. Model 4252(BL) Master Carriers are used with the systems. Model 142-R(242-R) is identical to Model 142(242) except that No. 4237(BL) Single Carriers and No. 4253(BL) Master Carriers are used.
