FAQ.

A closer look at Armor Flex and DuraFlex Wall Tunnels

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.
