The Institutional Lever Lockset is a reliable and durable lock that fits doors ranging from 1-3/4 to 2 thick with an arched stile, mortise strike plate or lip that makes it ideal for heavy-duty commercial use. It offers the highest level of security as it requires no separate key to retract the latch bolt providing restricted access while still being compatible with most exit devices, push plates, and lever escutcheons making it suited to comply with the ANSI/BHMA A156.3 2008 standard ensuring proper installation every time reducing replacement cost in long-term use for hospitals, schools, dormitories among others seeking to restrict access or enhance privacy while providing visual appearance compatible with other components and designs of facilities without compromise on performance or function at all times.
