Most new rectangular concrete or gunite pools accommodate an automatic pool cover by using our Underside track system. The track is concealed underneath the pool’s overhanging coping or housed within track channel. The cover mechanism is typically housed below the surface of the deck. Dual-Race track has been optimized for the Cover-Pools T4™ system. The wider track accommodates a 1-1/2″ pulley, which eases wear on the cable. In addition, it contains an integrated mechanical stop and contains a separate channel for the glider and fabric to reduce debris buildup.
