Important Fit Requirement

This patio-door insert occupies approximately 19" of the horizontal opening in the existing sliding door.

Before ordering:

1. Measure the patio-door track height.

2. Confirm that the height is between 75" and 80.25".

3. Measure the total usable width when the sliding door is open.

4. Subtract approximately 19" for the installed insert.

5. Confirm that the remaining opening is wide enough for people to pass through comfortably.

This is the regular-height model. It does not fit patio doors measuring 92.75"–96", which require a separate extra-tall version.

Four-Way Access Control

Select the access mode appropriate for your pet:

• In Only

• Out Only

• Full In and Out Access

• Closed and Locked

The indoor and outdoor sensors can be controlled independently through the app or the physical control panel.

Wi-Fi App Controls

The compatible High Tech Pet mobile app allows users to:

• Open and close the pet door remotely

• Activate or deactivate indoor and outdoor sensors

• Set customized weekly access schedules

• Create an unlimited number of access timers

• Select entry and exit permissions

• Adjust supported hold-open settings

• Review activity by day, week, month or year

• Review manual and sensor-activated openings

• Receive supported activity and malfunction notifications

• Access current operating instructions

• Receive supported firmware updates

Remote functions require a compatible mobile device and an active internet or cellular connection.

Collar-Activated Operation

The directional sensing system detects a compatible ultrasonic collar as the pet approaches. The panel opens for the authorized pet, remains open while the collar signal is detected and closes after the pet moves through.

Additional compatible collars can be purchased for multi-pet households. The supplied information identifies compatibility with High Tech Pet MS-5, RX-10 and BF-30 collars.

Automatic Closing and Locking

The lightweight door panel closes smoothly by gravity rather than being driven downward by the motor. After closing, its built-in deadbolt engages to help prevent access by animals that are not wearing a compatible collar.

If the descending panel encounters an obstruction, the automatic safety-retract system is designed to raise it again. Pet training and appropriate supervision are still required.

Patio-Door Construction

The insert features:

• Dual-pane Low-E tempered glass

• Heavy-duty aluminum frame

• Industrial-style powder-coated finish

• Spring-loaded adjustable top section

• Included weather stripping

• Included universal quick lock

The existing patio door slides against the installed insert. Compatibility can vary by track design, frame dimensions and lock configuration.

Training Your Pet

Introduce the automatic door gradually:

• Let the pet inspect the door while it is inactive

• Use the hold-open function during supervised training when appropriate

• Reward calm approaches and successful passage

• Introduce the moving panel and operating sound gradually

• Confirm dependable collar detection from both directions

• Do not force a frightened pet through the opening

Ideal For

• Sliding glass patio doors measuring 75"–80.25" high

• Large dogs weighing up to approximately 100 lb.

• Multi-pet households

• Renters or homeowners avoiding wall modifications

• Owners who want scheduled pet access

• Homes requiring remote door control

• Pets needing separate entry and exit permissions

Why It Stands Out

This kit combines an automated collar-activated pet door with a full sliding-patio-door insert. It requires no opening to be cut into the wall or household door and includes three collars, 12 batteries, weather stripping and a quick lock. Wi-Fi controls, access schedules, activity history and four-way permissions provide more control than a conventional patio pet-door panel.

Important Information

• This insert occupies approximately 19" of the patio-door opening

• Measure both track height and remaining walk-through width before ordering

• Fits patio-door heights from 75" to 80.25" only

• The pet opening measures 12.25" × 16"

• The 100 lb. rating is a general guideline; fit depends on body width and shoulder height

• Remote features depend on Wi-Fi, internet and app availability

• Manual controls remain available on the door

• The unit is not a substitute for responsible pet supervision

• Monitor weather, wildlife, traffic and other outdoor hazards

• Compatibility with every patio-door track and lock style is not guaranteed
