Add safety to any heavy-duty truck with a RETRAC convex mirror. This American-made, semi-bubble convex mirror provides an extra-wide-angle view of blind spots and the passing lane, featuring 8" diameter semi-bubble glass. It mounts with a 5/16" center-mount ball stud to maintain excellent rigidity, and the plastic ball allows for smooth, easy adjustment that will never be susceptible to rust.
The mirror head is constructed from polished stainless steel to be strong and highly rust-resistant. It is also tested against vibration and road salt to ensure maximum durability, mile after mile.
