The CRL Pinnacle Hinge is similar to our popular Geneva Series Hinge, but with one design change: Pinnacle has radius corners and beveled edges for a sleek appearance. Pinnacle Hinges accommodate 5/16" (8 mm) to 1/2" (12 mm) thick tempered safety glass, and are self-centering when within 15 degree of the closed position. Pinnacle Hinges are constructed of solid brass, and have stainless steel plunger tips, pins, and springs to ensure long service life and reliable door closure. The Pinnacle Hinge also contains the same Reversible 5 degree Pivot Pin featured in our Geneva, Cathedral, Roman, Ultimate, and Elite Series Hinges.
