Do not know which size to get? Here is a measurement guide to help you out.

Track Height Adjustment range is based on the measurement of your sliding door track height from the lowest point of your track to the highest point. Each Endura Flap Vinyl Panel has a 3" adjustment range. Review our Track Measuring Guide video for additional, detailed information The following standard adjustment ranges are available:

  • Short: 74 3/4" – 77 3/4"
  • Regular: 77 1/4" – 80 1/4"
  • Tall: 93 1/4" – 96 1/4"

If your measured track height does not fall within one of the ranges above, we can make a custom height! Custom height option may take up to 4 weeks to special order the glass and build the panel.

Installation Guide

Installation Information

One-Piece Panel

Installation icon Printable Version
Installation icon Difficulty Easy
Installation icon Steps 5
Installation icon Time Required 0.5 hours

Parts

  • Vinyl Panel Pet Door
  • Weatherstrip Seal Roll
  • Center Post Weather Seal Draft Stopper
  • Sliding Door C-Clamp Lock

Tools

  • Flathead Screwdriver

Please read instructions & notes thoroughly before installation.

Step 1 Loosen Height Adjustment Locks

Loosen Height Adjustment Locks
  • Loosen the height adjustment locks at the top of the pet panel with the screwdriver. This allows the spring mechanism to move freely up and down.

Step 2 Test Fit the Panel in Your Track

Test Fit the Panel in Your Track
  • You want to put the pet door in your track before applying any weather stripping to ensure it fits. If the panel fits well, proceed to the next step. See the Troubleshooting Section if you encounter difficulties.
  • To insert the panel into the top track, push up against the spring mechanism and swing the bottom of the panel up and over the threshold.
  • Seat the panel on top of the small guide rail in the track.
  • If you can't quite get it in the track, try swinging in from the outside as the outside track wall may be shorter.

Step 3 Apply Weatherstripping

  • Once you're sure the panel fits, remove it from the frame and lay it on its side on the ground.
  • For foam weatherstripping: Peel the backing off the foam weatherstripping. Press it along both edges of the panel, trimming as needed with scissors to ensure a snug fit.
  • For rubber weatherstripping: Clean the edge of your sliding door or window with rubbing alcohol to help the weatherstripping stick properly. Starting at the top or bottom, peel and press the strip into place with the folded edge facing indoors—align angled cuts if you have two pieces. For best results, apply the seal to the sliding door or window, but it can go on the pet door panel if needed.
  • Foam weatherstripping is applied onto both sides of the panel, but the rubber weather stripping only applies on the side of the slider door. Your panel will come with one type of weather stripping. You do not need both types.

Step 4 Install the Draft Stopper

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
  • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
  • This strip prevents air from leaking between the sliding glass door and the stationary panel.
  • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
  • Repeat step two to install the panel in your track.

Step 5 Install the Panel

Install the Panel
  • If you haven't already, insert the panel back into your sliding door track the same way you did earlier: pushing up against the spring mechanism and swinging the bottom into place. Push it snug into the side track!
  • Make sure everything is sitting securely.
  • Tighten the height adustment locks in the spring mechanism.
  • And that's it! Your pet door is installed and ready for use. Now, watch your pet strut through their new door like they own the place!

doggie door

my dog is still afraid to push the heavy flap open.. he will come in easier than going out.. still needs us to walk him to the door.. I think because he cannot see through the flap, it is cloudy..and heavy and makes noise when he goes through it. Also had to alter the installation with an added piece of wood due to it being a wood slider. cannot lock the door as it slides on the outside, not the inside of the house.. wish there was an option for that issues..

I like the product but….

It is well made. Easy to install. But my dog is terrified about going through it. If anyone knows what I can do…. I’d appreciate it.

Great dog door for those who are tired of being a door butler.

Great way to get my dog to go outside to use the restroom.

Bulldog loves it

Door is great! Has given our bulldog the independence he desires…and the staff at pet doors was so helpful in figuring out the size and correct door.
