CRL's Single Acting Glass-to-Glass Gate Hinges have been designed for use in pool enclosures, balconies, fencing, and any application where gates are required. Two 11/16" (17 mm) diameter holes are required for each side of the hinge (two on fixed panel and two on the gate). This heavy-duty hinge is set up to support weights from 55 lb (25 kg) to 132 lb (60 kg), and to support gate widths up to 48" (1.22 m) and heights up to 72" (1.83 m).
