The Estate Series of professional frameless shower door hinges are able to accommodate 3/8 to 1/2 inch (10 to 12 millimeter) tempered safety glass. An assortment of four styles, which includes Wall Mount and Glass-to-Glass types, gives style versatility and enables the designer/installer to develop custom enclosures limited only by their imagination. These superbly finished, solid brass cast Estate Hinges make it possible to mount 3/8 to 1/2 inch (10 to 12 millimeter) heavy shower doors without surrounding frames, so the door has a nearly "floating" appearance. The Estates heavy-duty stainless metal springs permit the door to swing 90° in and 90° out. A friction cam allows the door to be firmly maintained in any position, other than when inside 15° of the closed position, where it is tapered to assist in centering the door.
