Replacing an OE mirror loop on a heavy-duty truck is easy with RETRAC's wide range of mirror loops. Available in several different sizes, RETRAC loops quickly and securely mount onto an existing mirror assembly and accept a variety of west coast mirrors and convex mirrors. This particular loop measures 19-5/8" high by 5-1/4" wide. It is built with a plain mirror loop configuration, meaning it can accept most west coast mirror heads with clamp mounts (mirror head and mounting assembly not included). For long-lasting rust prevention, this mirror loop is constructed from stainless steel and features a polished finish for a bright, professional shine.
