Before ordering
A precise fit starts with the pet.
Measure the pet at the shoulder, confirm width through the chest, then choose the opening surface before selecting a flap package.
If this will live in glass, screen, kennel or an exposed exterior wall, verify the installation path before checkout.
Project check
Measure twice before it is made.
Keep shoulder height, body width, rough opening and frame dimensions labeled separately. Those numbers should agree before production starts.
FAQ.
A closer look at Wall-Mounted Pet Door - Up to 3 in. Walls
How is the configured price calculated?+
Standard selections use the exact retail SKU. Custom sizes inside the published specials table map to the applicable pricing tier. Larger custom doors scale the selected Giant configuration by area using the displayed oversized custom pricing rule.
Can I order a 45 x 50 custom size?+
Yes. Enter 45 x 50, choose whether that describes the flap, rough opening or overall frame, and the configurator will calculate the corresponding dimensions and oversized custom price. Production feasibility is confirmed before payment.
What should I verify before installation?+
Verify whether your dimensions describe the flap, rough opening or overall frame; then confirm pet dimensions, selected model, construction, frame clearance and the model-specific installation instructions. In-glass products require a professional glass installer.
