A hydraulic patch fitting for interior all-glass entrances uses a self-closing mechanism that is integrated in to the fitting, eliminating cutting into the floor to install a conventional floor closer. Only the base plate is anchored to the substrate. The fitting has adjustable closing and latching speeds and a 90-deg. hold option. Designed for 3/8-in. or 1/2-in. monolithic tempered glass, it holds doors as heavy as 220 lb. and 39-in. wide.
