The Markar Double Swing Hinge (DSH1000) allows doors to open 100 degrees in either direction. Paired with the Pemko Emergency Release Stop (ERS), the door has a clear passage and can open in reverse. The Corbin Russwin, BHSS and SARGENT BHW lock trim, cased open frame header and hinge jamb with single rabbet lock side jamb, make this the ultimate life-safety door opening solution for healthcare facilities.
