How Can I Extend the Glass Patio Pet Door for Taller Sliding Doors?

Modified on Thu, 9 Jul at 8:05 AM

Short Answer

The Glass Patio Pet Door fits sliding door openings from 1960–2120 mm (77.2–83.5") as standard. If your sliding door is taller, you can increase the overall height using optional Top Extensions and Middle Extensions, allowing the pet door to fit openings up to 2680 mm (105.5")


Which Extension Do I Need?


The extension you need depends on your sliding door opening height. 


Sliding Door Opening HeightRecommended Extension Configuration
1960–2120 mm (77.2–83.5")No Extensions
2120–2280 mm (83.5–89.8")1 × Top Extension (+160 mm / 6.3")
2280–2440 mm (89.8–96.1")2 × Top Extensions (+320 mm / 12.6")
2360–2520 mm (92.9–99.2")1 × Middle Extension (+400 mm / 15.7")
2520–2680 mm (99.2–105.5")1 × Middle Extension + 1 × Top Extension (+560 mm / 22.0")

Extension Options


Top Extension

  • Adds 160 mm (6.3") to the overall height.
  • Up to 2 Top Extensions can be installed.




Middle Extension

  • Adds 400 mm (15.7") to the overall height.
  • A maximum of 1 Middle Extension can be installed.






Top and Middle Extensions increase the overall height of the Glass Patio Pet Door, allowing it to fit taller sliding door openings. 



Measuring Your Sliding Door 


Before purchasing extensions, measure your sliding door opening from the inside bottom track to the underside of the top track.


Compare this measurement with the table above to determine which extension combination you require.






Important Considerations

  • A maximum of 2 Top Extensions can be installed.
  • A maximum of 1 Middle Extension can be installed.
  • Top and Middle Extensions can be combined to suit taller door openings.
  • Always measure your sliding door before purchasing extensions.
  • Note: Adding an optional Bottom Riser also increases the overall height of the Glass Patio Pet Door by 50 mm (2.0"). If you plan to use a Bottom Riser, remember to include this when checking your required door height.


Because sliding door openings vary between homes, customers should always measure their own door and confirm compatibility before purchasing accessories.
