Smart Alternative
to Dog Door
or Cat Flap

If you’re thinking of installing a doggie door or cat flap, think of installing LockLatch™ instead.

Here’s why:

  • LockLatch™ is less expensive.
  • It fits any door, window or hatch whatever it is made of and whichever way it opens (including glass sliding and patio doors).
  • You can adjust your door or window opening to suit your pet, anywhere between 3.6” to 6.7” using LockLatch™ or between 5.7” to 9” using PetLatch™ (the larger of the two).
  • LockLatch™ is less destructive to your existing door because you don’t need to cut a hole, making it a very good option if you’re renting.
  • It’s quick and easy to install and should only take you 10 to 15 minutes.
  • Doggy doors and cat flaps can provide easy access to burglars. Watch this video to find out how.
