3- Replacement retainer clip for Endura Flap Pet Doors
- Holds the magnets at the bottom of the flap
- Secures magnets in place for maximum insulation value

Product Details
The Endura Flap Retainer Clip holds the magnet(s) in for your Endura Flap Pet Door. The retainer clip fastens to your flap to hold magnets in place and prevent drafts. Here's how to install the retainer clip. Tip: you can put a little museum putty or double-sided tape between the magnet and flap to hold it in place while you put on the retainer bottom.
You can order additional or replacement magnets here. See how to adjust the magnets in the flap for proper orientation to attract the floating threshold (skip to 1:28). Here is the suggested number of magnets for each flap size:
Small flap: 1 Small Magnet
Medium flap: 1 Large Magnet
Large flap: 2 Large Magnets
Extra-Large flap: 2 Large Magnets
