These are a low profile light weight mounting bracket that add approx 0.9" each to the length of the actuator when installed. They fit on either end of the actuator and are chrome plated steel. Once installed, the brackets are free to rotate almost 180 degrees to give you the most flexibility with your application. Each bracket comes with a cross pin that has a small hole for P-clip or similar for quick release. Each mounting bracket order contains 1 bracket and 1 pin. Please note that they only fit the FA-35, FA-240, FA-150, FA-PO, FA-RMS, and mini track actuators.
