Its wide-angle convex glass provides a larger field of view for safer lane changes and maneuvering. The all-stainless steel construction resists corrosion, and the offset design allows it to be installed on either the left or right side. Replace this mirror when the glass is cracked, pitted, or the bracket is damaged.
