Liberty Pet Door for White Horizontal Sliding Windows

Product Details

The Liberty Pet Door for Horizontal Sliding Windows installs into a side-to-side sliding window without modifying the window or the frame.

It works with vinyl or aluminum sliders. The clear safety glass above the flap keeps the window insulating the way it did before, and the weather-resistant flap maintains a tight seal in normal weather.

The panel height is adjustable, and standard ranges cover track heights from 33.5" to 50" and from 54.5" to 60.5". Custom sizes are available for windows that fall in between or outside these ranges. The spring-loaded design holds the panel in place without screws or permanent modifications, which is why it works for renters.

The white finish is the same on both frame materials. Aluminum panels need a track at least 1" wide; vinyl panels need 1-1/4". Aluminum is the lighter and slimmer option; vinyl is the better insulator.

The clear vinyl flap stays flexible from 0°F up to 120°F. Pets can see through it, which helps with training and reduces flap-aversion in timid animals. Magnetic closures and pile weatherstripping keep drafts out. A smaller size is available for cats.

The flap cleans with dish soap and water. No special cleaners needed.

Each panel ships with a locking cover that drops in from the top to block the opening when you want the door closed off.

Made in the USA. Built to hold up to weather, daily use, and active pets.

Features:

  • Adjustable height: 3" spring-loaded range takes up slack between the standard sizes. Unsure what adjustment range to get? Pick the shorter of the two.
  • Clear vinyl flap: Easy for timid pets to learn. Holds up across normal weather.
  • Magnetic sealing closure: Keeps the flap closed in wind. Magnets adjust to temperature changes to maintain the seal.
  • Low maintenance: Flap cleans with dish soap and water.
  • Made in the USA: Aluminum or vinyl frame. Both white.

Parts

  • 1 Horizontal Window Pet Door
  • 1 Foam Weather Strip
  • 1 Center Post Weather Seal Draft Stopper
  • 1 Clamp Lock
  • Screwdriver

Tools

  • Scissors
  • Flathead Screwdriver

Please read instructions & notes thoroughly before installation.

Step 1 Release Spring Mechanism

  • 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 Check Panel Fit

insert panel into track
  • 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.
  • 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 FAQs if you have trouble.

Step 3 Apply Weather-stripping

apply weather stripping to panel
  • 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 Center Post Weather Seal

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home. It can be installed on either the back edge of the sliding window panel (Figure A) or the leading edge of the stationary panel (Figure B).
  • This strip prevents air from leaking between the sliding window and the stationary panel. Trim with scissors as needed.
  • Clean the edge of your window with rubbing alcohol before installing to assure a good seal.
  • Place the panel back into the window, then tighten the height adjustment locks to lock it in place. Installation complete!

LOCK DETAILS

Since you likely can no longer use your window’s original lock, we have provided you with an alternative locking method to keep your home secure.

Installing the window clamp: This clamp has a screw that tightens by hand to prevent the sliding door from moving beyond the clamp’s placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door’s raised track.

If you aren’t able to use the lock that comes with the panel: A great alternative to locking your sliding glass door is a Charley bar or dowel in the track. Both work off the same concept - they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.
