How To Measure A Gasket

  1. Establish how the gasket 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 Gasket Profiles page or your sample ring. Compare thickness, width and magnet width
  3. For flange-type gaskets specify dimesions from outside edge to outside edge, making sure to measure from the widest point of the gasket. For dart-type gaskets specify dimensions between the tips of the snap-in darts.

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.

Measuring Gaskets

  • Gaskets are guaranteed to 1/8" of specified dimensions
  • All gaskets are measured outside corner to outside corner unless specified dart to dart
  • Gaskets are custom made and, in most cases, cannot be returned
  • We will cut down gaskets made by Sure Seal. Each side of the gasket will lose up to 1/8" from the cutting process.
