1 Roll of Foam Weather Stripping
1 Center Post Weather Seal Draft Stopper
1 Locking Cover
Quick & Easy Installation: Release Spring Mechanism
Loosen the width adjustment locks at the end of the pet door insert with a flathead screwdriver. This allows the spring mechanism to move freely from side to side. Check Panel Fit
Insert the sash into the window track. Push against the spring mechanism and swing the opposite end into the window track. Gently release to check that the panel fits perfectly in your window track. Apply Weatherstripping
Remove panel from window track. Apply the foam weather-stripping by peeling back the paper and exposing the adhesive. Unroll it along the edge of the sash, pressing to ensure it adheres. Install on both the top and the bottom. Trim to fit with scissors. Mount Draft Stopper
Mount the Center Post Weather Seal Draft Stopper. This strip prevents air from leaking between the window frame when raised to accommodate the sash. Trim to fit with scissors. Reinstall the panel back into the window track. Tighten width adjustment locks.

How to Find Your Pet Door Size Find Your Flap Size Measure your dog to ensure that your flap is at least 1 inch above the highest point of their back (this may be their shoulders, mid-back, or tailbone).
Backyards and patios are typically a few inches lower than a home's floor level. Please ensure that your dog is comfortable stepping over both the step-over and the extra distance between the floor level and the outdoor ground; this is more important for doors with large step-overs or tiny dogs. Find Your Width Adjustment Range To find your width adjustment range, measure your sash track from the right-most corner of your window to the left-most. Make sure there is nothing blocking your measuring tape from reaching your frame's corner.
Your panel should have an adjustment range that encompasses the width of your sash window. Check Your Track Width The Sash Panel at least 1" of space in order to properly fit within the top and bottom track of your sash window.
Measure your bottom track to ensure that your panel will fit.
