Conventional Profiles

This door assembly uses a standard Hollow Metal profile.  This ensures it will fit seamlessly into your facility, whether for a mechanical room or a board room.

Hospital Stops

Hospital stops are available for medical applications, or anywhere cleanliness is a concern.  The hospital stop allows a mop or broom to be used unobstructed by the frame stop.  You may also want to consider using hospital tip hinges as well.
