The CRL Ultimate Series of professional hinges is able to accommodate 3/8 to 1/2 inch (10 to 12 millimeter) glass. A variety of two styles, Wall Mount and Glass-to-Glass types, gives design flexibility. The Ultimate Series Hinge is named primarily for its combination of design elegance and service life. Featuring the same beautiful rounded corners and beveled edges of the Pinnacle Hinge, the Ultimate Hinge is constructed entirely of stainless steel. This all-stainless construction gives the Ultimate Hinge a durability not usually found in brass hinges. The Ultimate has superior survivability in conditions of accelerated corrosion, such as seaside communities with high atmospheric salt levels. The Ultimate Hinge has stainless steel plunger tips, pins and springs to endure long service life and reliable door closure. It also has the same Reversible 5 Degree Pivot Pin featured in our Geneva, Cathedral, Pinnacle and Elite Series. A Custom Pivot Pin is available for "off-angle" installations.
