  • 1 Dragon Main Inner Flap - flexible, rectangular piece with the Dragon logo
  • 1 Dragon “U” Outer Flap - narrower flexible piece shaped like the letter “U”
  • 5 thread-Forming Screws - ½” long screws
  • 4 Frame Strike Plates - ½” x 1 ¾” steel plates with adhesive backing

Tools

Replacing the Flap

Step 1 Remove Screws

  • Remove the two screws holding in the U-shaped outer flap from the frame with a Phillips-head screwdriver.
  • If the screw head gets damaged, you can replace it with a new screw from the kit later.

Step 2 Remove Flap

  • Remove the old U-shaped flap, then remove the three screws holding the main inner flap.
  • Discard any damaged screws as necessary.

Step 3 Remove Magnets

  • Separate the magnets from your old flaps.
  • Unfortunately, the magnets must be sent to the trash, but your old flaps are recyclable.
  • Contact your local waste management and ask if they can recycle polyolefin elastomers or flexible polyethylene.

Step 1 FLAP INSTALLATION Main Flap

  • Install the main inner flap onto the frame with the three center screws. The logo should face you, away from the frame.
  • Take care not to overtighten; tighten just enough for the screw, flap, and frame to all be flush with each other.
  • The flap material will start to deform when overtightening begins.

Step 2 U-Shaped Flap

  • Install the U-shaped outer flap onto the frame with the two remaining screws.
  • The magnets should face towards the main flap and the frame.
  • The corners of the breakaway channel around the screw will bend outwards when overtightening begins.
  • Installation complete! If the flaps don't sit quite right off the bat, you can try massaging them into place.

Replacement easy to install

Dogs broke first door outer flap. Also added better magnets to help keep the flaps closed when the wind blows. We will see if this modification helps.

The door works great and was easy to install. The only suggestion that I have is to add washers to the screws holding the plastic flaps in place. They tend to come lose and you can only tighten the screws so much without damaging the plastic flaps. A washer or something similar would allow the screw to be tighten more without damaging the flaps. Overall very happy!
