The 449-107 Mounting Plate Retainer is a critical fastening component used across a wide range of PowrLiner, PowrTwin, and PowrTex line stripers and related equipment. It secures the mounting plate in position, ensuring that attached components such as pumps, engines, and control systems remain properly aligned and firmly held during operation.
This retainer is engineered to withstand vibration, shock, and the stresses of job site use. A properly functioning mounting plate retainer prevents loosening, misalignment, and potential damage to mounted components. Over time, retainers can become bent, corroded, or worn, compromising their holding ability. Replacing a damaged retainer restores secure fastening and ensures reliable equipment performance.
