The patented Magne Shade™ system uses small but very powerful magnets that are mounted on the inside of the windshield with a 3M peel and stick tape. Our shades are designed to fit your coach glass tight, we incorporate a simple and effective fabric adjustment system in our design so your shades won’t stretch out of shape and sag over time, as a snap type system can. Magne Shade™ is simply the best custom RV shading system in the market place.
