The MTRME6 rail mount extension set includes two 6-inch rail mount extensions. The extensions offset the davit arms 6 inches aft from the center of the rail, bringing them to a more vertical position. Shorter or longer extensions are available, from 3 inches minimum to 8 inches maximum; call to order. For offsets less than 3″, see Rail Mount Spacers. For angle and unique construction, consult a MarTek Davits team member.
