Our CRL Pinnacle 280 Series 180 Degree Pony Wall Mount Hinges are used in conjunction with the Pinnacle 180 Degree Glass-to-Glass Hinge for use with 180 degree pony wall applications. Previously, the tile or marble had to be cut to allow the wall mount hinge to be recessed. That adjustment aligns the pivot points between both hinges. To eliminate this time consuming step, CRL has produced these modified wall mount hinges with a shortened center block (containing only one centering spring), and a small back plate (with only two mounting holes). This allows the hinge to be mounted to the surface of the tile or marble, and have it's pivot point match up with the glass-to-glass hinge pivot point above. Pinnacle Hinges are self-centering, and contain a reversible 5 Degree Pivot Pin. In addition, Custom Pivot Pins are available to accommodate "off angle" installations. Made of solid brass with all moving parts (pins and springs) in stainless steel.
