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 18-1/2" high by 8-7/8" wide. It is built with a swedged mirror loop configuration, meaning it can accept RETRAC west coast mirror heads with stud 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.
