Our proprietary rubberized window channel replaces the inferior factory felt lining in Land Rover® Defender removable door tops and eliminates the famous glass ‘chatter’ common in these vehicles.

Made from virgin (non-recycled) EPDM rubber for it’s superior temperature and weather resistance, our window channel is impervious to ozone, making it fade-resistant. Upper flanges wrap out and around the window frame edge, so the glass never comes into contact with the metal, eliminating rattles. Inner surfaces are flocked to reduce friction allowing the window glass to slide freely in the channel.

Installed with simple hand tools, this product is designed to be barely noticeable on your vehicle yet greatly increase your driving enjoyment!

This kit is a complete solution, with enough window channel and rivets to restore both your driver and passenger side removable door tops. As an added touch, the kit also includes the correct #2 Pozidriv® ACR bit which prevents stripping of the hard-to-find screws that hold the window frame together.

    The Rubber Window Channels offered by Garrison Outfitters are fantastic! I was astounded by the quality of the channels. They were something I would have expected to come from Land Rover. The instructions were simple to follow and comprehensive in scope. Installation took a little time to get it right, but once they were in, it was perfect. I would recommend this product to ALL Defender owners. Outstanding product!!!

    Wow, I cannot tell you how satisfying that dull, rattle – free thump sound is when I close the door. Thanks again, love your product.
