The magnetic closures and weatherstripping keeps out drafts for advanced insulation and energy efficiency. 

The flap's low maintenance design, easily cleaned with just dish soap and water, frees up your time to enjoy life's moments with your pets.

  • 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.

Warranty

Liberty Pet Doors have a three-year warranty for normal wear & tear and manufacturing defects.
