Walk-In Hardware Terminology

General Terminology

  • Flush: When the door is closed, it is Flush with the wall. You cannot see the side of the door or the gasket.
  • Offset: When the door closes on top of the wall (the side of the door and gasket are visible when closed), it is an Offset closing door. The Offset is the distance between the front face of the wall to the front face of the door. Offset should always be measured on the hinge side.

  • Swing: The Swing of the door is established by standing outside the unit with the door closed. If the hinges are on the right, it is Right Swing. If they are on the left, it is a Left Swing.

Latch Terminology

  • Mechanical Latch: A Mechanical Latch has a lever that retracts the tongue to release the door.
  • Strike: The tongue catches the Strike, which is the piece mounted to the jamb.
  • Pull Handle: A Pull Handle does not have a strike. A door with a Pull Handle must have a magnetic gasket to hold the door closed.
  • Inside Release: An Inside Release is necessary with a Mechanical Latch or a Pull Handle that can be locked. This is a safety issue. There should always be a functioning inside release.

Hinge Terminology

  • Base: The Base of the hinge is the piece mounted to the jamb.
  • Strap/Flange: The Strap or Flange is the piece mounted to the door.
  • Cam-Rise/Cam-Lift: A Cam-Rise or Cam-Lift hinge raises the door slightly as it opens.
  • Spring Assist: A Spring Assist hinge adds extra closing force.
  • Reversible: Unless otherwise specified by right or left in the description, hinges in the catalog are Reversible.
