AL7211CRThe AL7211CR (1-3/8"ID) is the perfect holder for boats in the 16 to 31 ft range. Its economical price and small footprint (3"x 5") make it our most popular center rigger holder. The receiving tube of this marine grade anodized holder is set at a 45 degree angle. This is the perfect angle for boats where the mounting position is low and the cockpit is not extremely deep (e.g. mounting on T-Tops, Hard Tops, or Fly-Bridges). Compatible poles are 12 or 14ft in length and come standard in bright silver anodized finish with a Black Spike.Recomended poles for AL7211CR AO8712CR - 12 ft Center Rigger (Mk II) AO8714CR - 14 ft Center Rigger (Mk II) MX8712CR - 12 ft MX Step- Tube Style
