Increase visibility on your heavy-duty or light-duty truck with a RETRAC stick-on convex mirror. These add-on mirrors go anywhere, featuring a double-sided tape backing to adhere to virtually any clean surface, including glass, metal, plastic and even wood. Because the tape is waterproof, it easily outlasts the elements and keeps the mirror fixed in place, season after season. This particular stick-on mirror features 4" x 5-1/2" convex glass and is useful for adding visibility of the passing lane and blind spots. It is constructed from durable ABS plastic to be lightweight and always rust-free.
