LOCKING & SECURITY

Choose your locking option:

Our pet door inserts are fully lockable and secure, allowing your pet to come and go while keeping your home safe. Best of all, they install without any cutting or damage to your sliding doors.

You can install your Patio Link Pet Door Insert using one of the three simple options below:

  • Option 1) Lock Glass Sliding door ONLY: Locking Bracket

    Included with a new pet door insert purchase

    This option allows you to securely lock your sliding glass door by relocating the existing female latch onto the locking bracket on the pet door insert.

    Installation is quick and simple using a standard hand drill with 3mm bit, and the locking bracket is included free with your PatioLink Pet Door Insert.

    If your female latch sits inside the door channel, an Adaptor Panel will be required for installation.

  • Option 2) Adaptor Panel: Close BOTH Glass and Screen door into adaptor

    Adaptor Panel (Sold Separately)

    The Adaptor Panel allows you to securely lock both your glass sliding door and screen door when using a PatioLink Pet Door Insert.

    This slim panel installs alongside the pet door insert and is available in 2.1m, 2.5m, and 3m lengths, which can be easily cut to suit your door track.

    It’s the ideal solution if:

    • Your female latch sits inside the door channel, or
    • You want the ability to secure both the glass and screen doors

    Another great benefit is that it allows you to lock your screen door while keeping the glass door open, letting fresh air circulate while helping keep bugs out.

    Installation requires a hacksaw, hand drill, and pliers, and like all PatioLink products, it installs without damaging your doors, making it perfect for renters.

  • Option 3) L Profile for Stacker doors

    (Sold Separately)

    For stacker sliding doors where the gap between the glass door and screen door is greater than 11 cm, both an Adaptor Panel and an L Profile Extender are required.

    The L Profile Extender attaches to the Adaptor Panel using pop rivets, extending the reach up to 17 cm to suit wider door gaps commonly found in stacker door systems.

    This ensures the pet door insert can be installed securely and function correctly with larger door clearances.
