A clean, built-in pet door installed directly into replacement glass that preserves your door’s function while delivering a permanent, custom look with flexible sizing and professional-grade construction.

    Designed for both single-pane and double-pane glass doors, this innovative pet door allows your furry friends to come and go as they please without compromising the space and functionality of your sliding glass door or hinged door.

    The Hale pet door is specifically designed for glass doors, offering a space-saving alternative to traditional panel pet doors. With eleven different sizes available, this pet door accommodates pets of various breeds and sizes. The extruded aluminum frame and steel-reinforced corners provide exceptional stability, ensuring long-lasting durability and performance.

    To Complete your order, you will fill out a short electronic questionnaire (link on your order confirmation email) and need to  know the following before we can begin building your pet door:

    • Single pane glass must be no more than 3/16" thick and comes with only one flap
    • Double pane glass (single pane over 3/16" thick) has your choice of 1 or 2 flaps
    • Glass thickness is needed, should not be an estimate, because this will determine if your installation needs build outs or comp strips
    • Type of door being installed in (if sliding glass door, will need to know if the slider, slides inside or outside the fixed, non-operational panel)

    Glazier Required for Installation: Because existing tempered glass cannot be cut, this application requires replacing the entire pane of glass. Glass cutting, tempering, and installing a dog door in a glass door require a glass professional. It is always best to have the pet door in hand before ordering the glass so that you have the exact dimensions needed.

    Single-Pane Model: Fits tempered safety glass up to 3/16" and comes with a single flap only. If you have single-pane glass over 3/16" thick, you will need to order the double-pane model. Includes Comp Strips.

    Double-Pane Model: Fits glass thickness from 1/4" to 1-3/8". Can be used in glass thicknesses 1-3/8 to 2" thick with a build-out that will be included in the order. The standard order of this model comes with double flaps and an interior security cover, but it can be ordered with a single flap. Includes Comp Strips and Buildout. 

    Please Note: For sliding glass doors that slide inside the fixed panel, the pet door should be placed on the slider. For sliding glass doors that slide outside the fixed panel, the pet door should be placed on the fixed panel. This is to ensure the slider is able to fully open and not blocked by the lock or potential build-out.

    Warning: Thermo-Tru brand sliding glass doors require a specialized glazier for installation. Make sure you do not have a Therma-Tru pet door before purchasing. 

    Installation & Fit

    • Fits single-pane and double-pane glass doors where the entire glass panel can be replaced
    • Mounts within a new glass unit supplied and installed by a local glass professional
    • Secures as part of the glass panel rather than attaching to the door frame or track
    • Requires full pane replacement because tempered glass cannot be cut after manufacturing
    • Ships as the pet door unit to be integrated into the final glass order after purchase details are completed
    • Works with standard hinged or sliding glass door panels that can accommodate a custom glass insert
    • Non-standard door configurations or specialty glass may require additional coordination with a glazier

    Best Suited For

    Ideal for:

    • Homeowners who want a seamless, built-in look without a visible panel insert
    • Doors where maintaining full use of the sliding or hinged opening is important
    • Buyers comfortable coordinating with a local glass professional for installation
    • Projects where a permanent solution is preferred over removable or temporary optionsHomes prioritizing a clean aesthetic with minimal visual disruption to the door
    • Pets that need consistent access without sacrificing door functionality or space

    Not ideal for:

    Situations where a removable or DIY-friendly option is preferred such as Endura Flap Thermo Panel for sliding glass doors
