Data Sheets

  • Can these drop down seals be cut down?
    Yes - you can cut down these drop down seals. Please buy the most appropriate size for your door. For example, an 800mm door width requires an 830mm seal.
  • What is the difference between surface mounted and rebated seals?
    Rebated seals are hidden in rebates, making them ideal for doors which can be modified which also want to look as unaltered as possible.Surface mounted seals are easier to install and simply fix onto the exterior part of the door. Oftentimes they are more expensive, however, although are appealing due to the quick install time, which could also save you money.
