Give a large dog a way to pass through a door while helping limit the air and outdoor conditions that can enter through an open pet-door flap. The three-flap design is made for year-round use, and the adjustable tunnel accommodates a stated range of door thicknesses. Its white finish suits a range of door settings.

How does the three-flap design help protect against weather?

The door uses two magnetic outer flaps with an insulated center layer to help reduce drafts and the transfer of outdoor temperatures. The design also helps reduce wind, rain, snow, and insects entering through the pet-door opening. For households where a large dog or multiple pets use the door repeatedly, the rigid steel outer frame is designed to resist bending and withstand daily use.

• Three flap layers combine magnetic outer flaps with an insulated middle layer.
• The steel frame is designed for stability and impact resistance.

Will this dog door fit my existing opening and door?

It fits compatible large PetSafe Extreme Weather cutouts measuring approximately 11.2 in W × 18.1 in H (28.4 × 46 cm), and its telescoping tunnel adjusts for doors 1.7–2.4 in (4.3–6.1 cm) thick. Measure the existing cutout and door thickness before choosing this replacement so the opening and tunnel dimensions match. The tunnel is intended for common wood, PVC, and metal doors, whether installed on an interior or exterior door.

• Compatible cutout fit is intended to replace an existing opening without enlarging it.
• The door is white, with an adjustable telescoping tunnel.

What comes with the URSPET large dog door?

The package includes a template, mounting hardware, screws, and instructions for installation. An integrated lock handle gives you a way to control pet access from either side of the door. The lock handle is part of the door, while the included template and hardware support fitting the unit to a compatible door.

• Installation items: template, mounting hardware, screws, and instructions.
• Access control: integrated lock handle operates from either side.

Can I replace the flaps without replacing the whole door?

The flap design is made to work with compatible PetSafe Extreme Weather large replacement flap dimensions and URSPET replacement flaps, allowing future flap maintenance without replacing the entire pet door. Replacement compatibility depends on matching the flap dimensions, so compare the existing flap measurements before ordering. This makes the door suitable for owners who want a compatible replacement option for the flap assembly over time.

• Designed around compatible PetSafe Extreme Weather large flap dimensions.
• Also designed for URSPET replacement flaps; verify flap dimensions for compatibility.

The URSPET large dog door is suited to households with large dogs or multiple pets that need a door-mounted passage and a three-layer barrier designed to reduce weather transfer. It is a fit for compatible large PetSafe Extreme Weather cutouts and doors within the stated thickness range, with access controlled by its integrated lock handle. Its steel frame, adjustable tunnel, and compatible replacement-flap design bring those practical features together in one door unit.
