What size pet door should I choose?

If you are unsure what is the best size for your doggie, you can do a test at home to visually see and decide what is the best flap opening.

Simply open your sliding door to the width of the flap (eg. Medium Flap width 21cm) and then place a measuring tape inside the very bottom of the track of your glass sliding door and measure up the flap height (eg. Medium Flap Height 38cm), sticky tape a piece of cardboard at the top where the flap height meets (eg. Medium 38cm) and let your doggie go through the opening.
See our sizing chart. Our Flap Heights Include 5cm rise at the bottom.

NOTE: When choosing what is the best flap size for your doggie, make sure that the top of your doggies back is going through nice and straight without having to bend down.

Your FIRST STEP is to measure your Glass Sliding Door Height – VERY IMPORTANT!

Please measure your glass sliding door height from the inside bottom channel to the top inside channel. Our standard height pet door inserts fit height between 2.0-2.1m tall.

If your door is taller than 2.1m it means you will require a custom height pet door insert. You can choose one of these two custom height options:

– Taller Frame and Glass, or

– Standard Pet door insert with a Window Extension on top

Custom Height Pet Door Inserts


Our pet door inserts are fully lockable and secure without any damage to your sliding doors.

You can choose how you like to install your pet door insert – one of three options below:


FREE with Patio Link pet door insert purchase!

Locking bracket allows you to lock your GLASS Sliding Door ONLY.

Simply install a locking bracket to your pet door insert, transfer your current female lock onto the locking bracket and securely lock your glass sliding door. Very easy to install!

Tools required for installation: Hand Drill.

Option 2: ADAPTOR (optional)

Adaptor allows you to lock BOTH GLASS and SECURITY FLY SCREEN DOORS.

An adaptor is a long skinny panel that gets installed next to pet door insert. It allows you to securely lock both fly screen and glass sliding doors and it created an excellent seal and closure.

Wonderful feature about adaptor is that you can lock your security screen door into adaptor, enjoy breeze coming inside your home and keep unwanted bugs outside!

Tools required for installation: Hack Saw, Hand Drill, Pliers.


Another way you may like to consider to install your pet door insert is to install pet door in a corner where your fixed glass panel is.

You will need to look for screws that are holding your fixed glass panel, unscrew them and carefully slide your fixed glass panel across and fit a pet door insert in a corner. Then secure the fixed glass panel in a new position with a couple of screws.

Doing installation this way means you do not need a locking bracket or an adaptor and your main entry and locking remains untouched. When you move house, you just undo everything and put it back in original position.

Our pet door inserts are DIY Installation, however if you need help with installation we do have handyman contact.


So easy to use, just simply slide the aluminium flap cover over the flap and the spring plunge will lock your flap in place when you dont want your doggie or cat to go through.
