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 DuraFlex Low-E Patio Panel

How do I choose the correct size?+

Measure the widest point of the pet and the height needed for a natural passage, then compare those measurements with the exact opening shown for each SKU. Do not transfer a size label from another door family.

Is the wall or patio hardware included?+

Wall-mount models include the matched tunnel, and patio models include the full-height low-e insert. Door-mount models are for compatible hinged doors unless the product page states otherwise.

Can I order a custom opening in this model?+

These products use the verified standard openings shown in the selector. For a non-standard opening, use the custom-size collection instead of altering a listed model in the field.
