Check Your Frame

This includes checking the color and frame material. Most inserts are made out of aluminum. If you have a vinyl framed slider, please take note that our aluminum inserts can still work. There is more standardization in the newer vinyl framed panel doors. These inserts are limited in flap and track sizes. The manufacturer of the only vinyl framed inserts is Ideal Pet. Please check our site for their products. If you needed a different color than we offer, your insert can be painted over. If you are going to paint over it, we recommend a white color since that is easiest to cover up.

Advantages of vinyl inserts:

  • The insert will mate with most sliding patio locks
  • You will not have to worry about whether the rail of your track is a problem or not
  • Having the same material in your insert and frame will give it a natural look

Last Minute Considerations…

Worried about bugs flying in between the screen and patio pet door? Check out the Bug Warden, it can solve a problem you may not have considered.

Do we not have your track size? If this is the case, you may need a custom panel height. The Hale and Thermo Panel 3e can be made to fit just about any height. The Fast Fit can be made to fit heights above 80 inches.

Wondering how to lock the pet door? Each pet door comes with its own security cover to restrict access through the flap.

Need an electronic solution for your sliding glass? We have a few products to consider. Most will require your pet to wear a collar key to signal the flap to unlock. We have a microchip option for small dogs or cats. These are the best solutions to keeping unwanted critters from entering your home!

Deciding on single or dual pane?  Dual pane glass insulates much better than single pane and, as well, attenuates noise much better. If you’re going to live with the pet door for a long time or if you’re planning 4 season use, it might be worth getting dual pane.  If you live in a temperate area, single pane may be just fine. You can tell what type of glass you have by placing a finger on both sides of the glass. If they look like they’re touching, you have single pane; If they stop about 1/2″ apart, you have dual pane.
