Industrial Extension Door Cable Set
Heavy-duty extension spring cable set sized for industrial and commercial sectional door applications where increased cycle count, door weight, and operational demands exceed standard residential specifications. The set includes a pair of 1/8” × 168” 7×19 strand cables — the flexible, fatigue-resistant construction suited to high-cycle extension spring systems — alongside a pair of 3/32” × 156” 7×7 strand cables for installations requiring a stiffer, abrasion-resistant cable path. Industrial extension spring doors operate under higher spring tension and heavier door panel loads than residential systems, placing greater cyclic stress on the cable at the pulley and bracket attachment points; having both strand constructions available in a single set lets contractors match the cable specification to the door system and spring configuration without ordering separately.
