Product Details

Product Details

This magnet kit allows you to adjust how firmly your Endura Flap closes, giving you more control over how your pet door performs in real-world conditions. It is a simple upgrade that can make a noticeable difference in comfort.

Better Seal When It Matters
By adding magnets to key contact points, the flap is guided back into place more securely after each use. This helps reduce gaps that allow outside air to enter, especially in windy environments.

Flexible for Your Pet
Not every pet needs the same level of resistance. The ability to add or remove magnets means you can dial in the right balance between a secure seal and easy access for your pet.

The magnets install directly onto your existing flap system without requiring permanent changes. This makes it easy to improve performance without replacing your current setup.

Built for Daily Use
Made to handle repeated use, the magnets are designed to maintain their strength over time, helping your pet door continue to perform consistently in changing conditions.
