Product Details

Product Details

Retainer clips play a critical role in keeping your Endura Flap performing the way it should. By holding the magnets in the correct position, they help ensure the flap returns into place cleanly after each use.

Restore Lost Performance
Over time, clips can wear down, loosen, or go missing, which can impact how well the flap seals. Replacing them is a simple way to bring your pet door back to its intended level of insulation and efficiency.

The updated plastic design improves durability compared to older versions while maintaining a lightweight and easy-to-handle form. It is a straightforward upgrade that supports long-term performance.

Easy to Install
These clips attach directly to the flap and can be secured with light adhesive if needed. Installation is quick and does not require changes to your existing pet door setup.

Small Part Big Impact
While simple in design, retainer clips have a direct effect on how well your pet door performs. Keeping them in place helps reduce drafts, improve sealing, and maintain a more comfortable home environment.
