Generous opening for big dogs

The flap opening measures 18.7 x 9.92 inches, making it easier for large pets to pass through without turning. The unit is designed to support pets up to 110 lb, and a locking panel gives you simple control over when your pet can go outside or back in.

  • Locking panel helps manage access when you’re not home

Insulation and weather sealing for year‑round comfort

A multi‑layer system combines 1 insulated flap plus 2 magnetic flaps with dust seals. This setup helps block drafts, reduce dust intrusion, and minimize external noise, supporting a cozier living space as weather changes.

  • 1 insulated flap + 2 magnetic flaps + dust seals work together to curb drafts
  • Designed to help maintain indoor temperature with frequent door use

Durable, rust‑resistant construction

Made from premium aluminum alloy with reinforced welding, the door is sturdy yet lightweight for easy handling. The corrosion‑resistant profile is built for long‑term use through seasons and varying conditions.

Everything you need is included for a straightforward wall or door install. It fits wall thickness from 3.95 to 7.5 inches with a cutout size of 18.9" H x 10.6" W. A cutting template, guide paper, and detailed instructions help you measure and cut accurately.
