The RAM Mounts Large Fishfinder Mount gives anglers a stable, adjustable platform for oversized marine electronics when staying on structure and tracking fish for bass, walleye, and salmon. This complete flat-surface, drill-down mount supports large displays and uses RAM's ball-and-socket system to deliver near-infinite adjustability, so you can dial in clear viewing angles from the bow or console as conditions change. A universal mounting bracket with multiple hole locations fits a wide range of fishfinders and offers the option to drill additional holes for a precise match when needed. Built from powder-coated, marine-grade aluminum, the mount absorbs vibration and holds heavy units steady in choppy water.Flat-surface, drill-down mounting solution for large marine electronicsBall-and-socket system provides near-infinite viewing adjustmentUniversal mounting bracket with multiple hole patterns; additional drilling may be requiredPowder-coated, marine-grade aluminum construction for durabilitySpecifications:Top plate dimensions: 3' x 11'Bottom plate dimensions: 3.68' diameterBall size: D Size 2.25'Weight capacity for standard use is 6 lbs.Weight capacity for heavy-duty use is 5 lbs.Includes 4 .312' x .187' Shoulder WashersManufacturer's lifetime warrantySizeOverall height (in.)Socket to socket length (in.)Weight (lbs.)Short8 1/83 3/53 29/50Medium11 1/26 22/254 13/20
