  • Sheet Door Astragal Replacement

    DBCI demonstrates step-by-step how to replace the astragal on your metal roll-up door.

  • The astragal is the strip of rubber that runs along the bottom of your storage door and acts as a barrier seal to protect a storage unit from draughts and dirt.

    To replace it, simply raise the door so the astragal is even with the latch hole on the side of the guide. Using a flathead screwdriver, open the crimped aluminum on each end of the astragal channel. Slide the used strip through the latch hole and discard. Spray a light lubricant along the inside of the channel and feed through a new astragal strip of appropriate length. Use a pair of vise-grips or pliers to re-cramp the ends.
