Parts

  • 1 Vinyl Panel Pet Door
  • 1 Weatherstrip Seal
  • 1 Center Post Weather Seal Draft Stopper

Tools

  • #2 Philips head screw driver
  • Non-metal hammer
  • Scissors

Please read instructions & notes thoroughly before installation. If you need to lower the step-over height, complete steps A-C from the end of these instructions before installing the panel in your track. The step-over height can only be adjusted for the Large Cat Flap size.

Step 1 Loosen Height Adjustment Locks

  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.

Step 2 Insert Panel Into Track

  • Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
  • If you can’t clear the track, try swinging in from the outside, as the outside track wall may be shorter. If the panel still doesn’t fit, see the FAQ for guidance.

Step 3 Apply Weatherstrip

  • Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
  • Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.

Step 4 Place Panel In Track

  • Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.

Step 5 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.

The following steps are only applicable if you need to lower the step-over for the Large Cat Flap size from 4.5" to 2.5" (step-over not adjustable for Cat Flap size). If you need to lower the step-over, complete these steps before installing the panel in your track.

Step A Separate Flap Frames

  • Lay the entire panel on a flat surface. Remove the hole plugs covering the four frame screws and set them aside.
  • Use a #2 Phillips head screwdriver to unscrew the four frame screws from the flap frames to separate them, then set them aside.

Step B Loosen Side-Screws

  • Loosen both the middle and bottom sets of side-screws by one turn.

Step C Move the Cross Piece

  • Once the bottom and middle side-screws are loosened, slide the crosspiece at the bottom of the panel up to the middle of the panel.

Step D Tighten the Screws

  • Once the cross piece is in place, tighten the bottom side-screws and middle side-screws.

Step E Reattach Flap Frames

  • Reinstall the pet door assembly to the panel by sandwiching the interior and exterior frames on either side of the panel directly below the cross piece that was raised in Step C.
  • Insert the four frame screws through the pet door frames.
  • Do not fully tighten the screws until all four are inserted and the pet door is leveled.

Step F Add Hole Plugs

  • Use the wooden of a hammer, a rubber mallet, or another non-metal tool to tap the hole plugs back over the four frame screws.

Whiskers & Windows Locking Details

  • Locked: Both tabs on the outside.
  • Out-only: Both tabs to the right.
  • In-only: Both tabs to the left.
  • Unlocked: Both tabs in the center.

Installing the Clamp Lock (Sold Seperately)

  • 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.

Alternative Locking Method

  • 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.

FREQUENTLY ASKED QUESTIONS

What if my panel is slightly too tall?

You can trim up to 3/4” off the spring- loaded adjustment piece at the top. This can be done by removing the adjustment pieces with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low or you will not be able to put the top back on.

FAQ

Will this fit all vinyl doors?

This will work in doors that have a recessed track at least 1 1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail.

Does it lock?

We do include a c-clamp lock. It is not designed to mate with your existing sliding door lock. You can also use a Charley-Bar or dowel in the track.

Can I install it myself?

It is meant to easily be put in and removed. You just have to loosen the screws at the top, fit it into the track, and then tighten them. Then to remove it you simply loosen them again and pop it out.

If you can remove it what prevents intruders from taking it out?

The thumb screws are on the inside of the house so you can't loosen them from the outside.

Can you lock the pet door?

The pet door has a four-way lock so you can set the flap to completely locked, unlocked, in-only, or out-only. 

How to I measure for it?

You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track.

Does it come in any color other than white?

No, but the you can paint the vinyl to match.

What if my track is wider than 1 1/2"?

It can still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly.

Does your door have to be vinyl?

No, not as long as the track height and width meet the panel specs.

Is the flap flexible?

The flap is rigid, lightweight acrylic. Many cats prefer rigid flaps over flexible flaps.

Is the flap clear?

Yes, the flap is clear. 

Will this form condensation like the aluminum panels?

Nope! That is one of the great things about the vinyl framing is you won't have the the condensation on the inside of the house.
