Parts

  • Sash Window Pet Door

Tools

  • Flathead Screwdriver

Please read instructions & notes thoroughly before installation.

Step 1 Release Spring Mechanism

  • Release the automatic width adjustment locks by loosening the screws with a screwdriver. This allows the spring mechanism to move freely from side to side.

Step 2 Check Panel Fit

  • Insert the sash into the window track. Push against the spring mechanism and swing the opposite end into the opposite window track. Gently release.

Step 3 Apply Weatherstripping

  • Remove panel from window track.
  • Apply any optional 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.

Step 4 Insert Sash Panel

  • Put the panel back into the window track. Tighten width adjustment locks with a flathead screwdriver.

LOCKING YOUR WINDOW

For a permanent lock, install a wood screw in the track immediately above the window on both sides. You will no longer be able to raise the window. For a temporary lock, place a removable wooden dowel or Charley bar in either track above the window, shown in Detail 1.

HEIGHT OF YOUR WINDOW

Make sure you place steps or ramps leading to your pet’s door at a height that works! When they go through the flap, the top of the flap should be at least 1" (2,5 cm) higher than the top of their back. Watch your pet and adjust as needed to keep them comfortable.

How to Measure Your Sash Window for a Pet Door

FAQ

What do I need to know/measure before I order?

First raise up your window and check that it can go up far enough to be left with an opening 15" high. Next measure the width of the track from left to right, including going inside the track on both sides. Last measure how wide the track is that the window slides in (needs to be at least 1"). 

How wide does the track have to be for the Whiskers & Windows Sash to fit?

Track width needs to be at least 1" thick.

Can I choose what side the door is on?

It comes standard on the left, if you are looking from the inside of the house. You can switch the side of the flap by removing the four screws in the flap frame to remove it from the panel, then install the flap frame back in the panel upside down.

Is this easy to install?

Yes this is very easy to install and only requires a flathead screwdriver to adjust the topper locks. 

What if I mismeasured?

If you've mismeasured, you may be able to fix it. To make your sash cat door about 3/4" wider, you may purchase a width extension (or make your own using 1" x lumber). To make your window kitty door insert slightly shorter you may trim the side flanges on the spring loaded adjustment piece with a hacksaw or a jigsaw with a metal cutting blade.

Will this fit dogs?

Not easily. We recommend getting a sash panel that is big enough for dogs to go through, such as the Dragon Sash Panel Pet Door.
