    • Beckson Port Replacement Gasket
    • Applications: Beckson Opening Portlights
    • Sold (1) Per Package

    Please Read Installation Instructions Carefully.

    • Remove old gasket by pulling out of groove
    • Before installing a new gasket make sure groove is clean and dry
    • Do not use any type of lubricant and make sure the screen is in place, smooth side facing toward you and leg down into inner groove, before installing the new gasket
    • The part of the gasket that fits into the groove is the smaller, thinner part which is called the "leg"
    • Start in between the two hinges by positioning the seam of the gasket over the outer groove of the window frame
    • Work from this location toward the top right corner
    • Guide entry of the leg of the gasket into the outer groove with your hand by bending the gasket out and away from the frame 90 deg
    • Pushing down firmly at the 90 deg point with your index finger or thumb will seat the gasket into the groove
    • Proceed slowly, seating 1/4" at a time
    • As you work around the corners, slightly stretch the gasket so extra material doesn't cause a crease or a bump
    • After seating the gasket around the first corner by hand, take the end of a wooden ruler or similar tool with a dull flat end and press down on top of the leg of the gasket to complete seating the first corner
      • This is accomplished when the small ribs on the leg of the gasket are completely inserted into the groove
      • Continue on to the following corners in the same manner until the gasket. is completely seated in the groove
      • Seating the last corner will require slight stretching of the gasket
      • If the gasket pulls out of the opposite corner, this indicates you need to go back to that corner and stretch the gasket a little more along with pushing it down into the groove further
      • Take extra care to make sure the leg is completely seated near the hinges and latches
    • The complete gasket should now be smooth and uniform

    Installation Notes:

    • These gaskets require some effort to install
      • A tight installation assures a water tight seal
    • You sent me the wrong gaskets !!!
      • The gasket you took out of your port is flat
      • The one you received is round and shaped funny
      • All gaskets start out like this
      •  It's a matter of feeding the leg of the gasket into the groove in the frame.
    • Tip from the field:
      • Just before installing the gasket, carefully stretch / flex it a bit
        • Start next to the seam holding the gasket between the thumb and forefinger of each hand, with about an inch of gasket between
      • Give it a little stretch
      • Work your way around the gasket
      • Be careful not to pull on the seam or over stretch
      • This flexes the rubber a bit (like stretching a balloon before blowing it up) removing the stiffness
      • It also stretches it out temporarily just enough to make it fit better with almost no pull on the final corner
