Instead of taking up space in the track of your sliding glass door, these through the glass dog doors allow for free range to and from the slider, making it easier on you and your guests.

Can I just cut my existing glass?

If you have dual pane or tempered glass you will need to have a local glass shop make a piece of glass with a notch, as you can't cut that without it shattering.

Can this door go into a slider?

It is possible, however, it will stick out so there may not be enough clearance for the sliding door to open all the way. We recommend that the doors be installed in swinging doors or sidelights.

Do I need to hire an installer?

Yes, we highly recommend having a professional do the installation. 

Is the pet door clear?

The flap is a clear flexible vinyl with magnets and weather stripping to help seal it up. The more insulating double flap option is only available if you have dual pane glass.

Why do you need my exact glass thickness?

The manufacturer will include a build-out for anything other than 3/16" and they send the proper one out depending on the thickness.

My glass is single pane, but it is not 3/16"?

In that case, you must order the double-pane version and specify your exact thickness.

Does this come with a cover?

Yep, it will come with a cover to close off the dog door when not in use. 

Can small and large pets share this door? 

Yes, this is a great door for multiple size pets to use.

Are replacement parts available?

Yes, you can find them here.

Is there a warranty?

Hale offers a 5-year pro-rated warranty.
