How to Measure a Gasket

How To Measure A Gasket
  1. Establish how the gaske mounts to the door. It should fall into one of four styles: screw-on, snap-in, push-in or panel gripper.
  2. Compare your gasket to the profile pages or your sample ring. Compare thickness, width and magnet width.
  3. Follow the measuring directions on the Profile pages, making sure to measure from the widest point of the gasket.
Make Sure To Check These Items
  1. Note the number of sides, most walk-in gaskets have only 3 sides.
  2. Some gaskets do not have a magnet on the hinge side. If this is the case for a 3 sided gasket, be sure to note if the door is hinged left or right. For a 4 sided gasket, note which length has no magnet.

Latches & Handles - Terms used in relation to latches and handles:

  • Adjustment is an area with a series of parallel grooves and slotted holes that will mate with another grooved area. While the screws are loose, the latch or strike can be moved the full travel of the slotted holes. When the screws are tight the grooves mate, holding the item at the proper adjustment. Using the incorrect screw size can reduce or eliminate the adjustment. A Micro turn strike can be adjusted by backing out the set screw, screwing the hook in or out, and re-tighten set screw.
  • Edgemount refers to a latch that mounts vertically on the side of the door as opposed to mounting on the front face of the door. Most reach-in doors have edgemount latches.
  • External Mounting most often is used in reference to pull handles. The screws for the handles install from the front of the door.
  • Internal Mounting most often is used in reference to pull handles. The screws for the handles install from the inside of the door.
  • Latch Only refers to the body of the latch which mounts on the door.
  • Latch Complete refers to both body and strike.
  • Magnetic/Mechanical refers to the catch mechanism. Some latches have a magnet that holds the door closed. Mechanical latches have a hook that holds the door closed. Some latches are both mechanical and magnetic.
  • Offset is the distance between the face of the unit and the front of the door. Offset will only apply to a surface mount latch.
  • Offset Handle refers to a vertical latch with a "dog leg" lever. The lever extends past the door allowing easy access in tight situations.
  • Screw Centers are used to help identify hardware. The measurements are taken from the center of the screw holes.
  • Straight Handle refers to a vertical latch running flush with the edge of the door. This provides additional protection from abuse.
  • Strike Only refers to the catch which mounts on the face of the box.
  • Surface Mount refers to latches that mount horizontally on the front face of the door.

Hinges - Terms used in relation to hinges:

  • Adjustment is an area with a series of parallel grooves and slotted holes that will mate with another grooved area. While the screws are loose, the hinge can be moved the full travel of the slotted holes. When the screws are tight the grooves mate, holding the item at the proper adjustment. Using the incorrect screw size can reduce or eliminate the adjustment.
  • Cam-Rise refers to hinges with a self closing feature. As the door opens, the cam lifts the door. The weight of the door closes the door.
  • Edgemount refers to a hinge that mounts vertically on the side of the door as opposed to mounting on the front face of the door. Or the top and bottom of the door.
  • Offset is the distance between the face of the unit and the front of the hinge.
  • Pivot hinges mount on the top and bottom of the door allowing the door to pivot open.
  • Screw Centers are used to help identify hardware. The measurements are taken from the center of the screws holes.
  • Spring Assist Hinges create a self closing door. They must be used with a magnetic gasket or use a non-magnetic gasket and a magnetic latch. Do not expect the spring's power to hold a door closed or close a mechanical latch.
  • Surface Mount refers to hinges that mount horizontally on the front of the face of the door.
