Grand Slam Outrigger Mounts are designed for soft-or hard tops up to 2" thick. Mounts are sold in pairs, either alone or as part of complete mount/outrigger pole kits. Versatile Grand Slam 370 Outrigger Mounts conveniently operate from under your top with an offset handle for outboard angle and crank for vertical height adjustment. Grand Slam 270 Mounts adjust for height from above the top but like the Grand slam 370 offer easy adjustment for outboard angle from the helm. Grand Slam 170 Mounts (New for 2012) operate from above the top and feature an exclusive Twist-n-Lock rotator collar that locks in 12 fishing positions. Delrin bearings and an internal locking mechanism ensure smooth adjustments. Rugged, sure-grip knob adjusts and locks to desired height and laydown position for safe trailering and navigation under bridges. Designed for use with standard 1-1/8x9D butt OD outriggers. Stainless steel arm with locking feature ensures TACO outriggers remain securely in place. Look for outrigger-ready tops with pre-drilled mounting plates on Boston Whaler, Grady White, Glacier Bay, Fountain Powerboats, and Hydra-Sport.Includes:Grand Slam 170 Outrigger MountStandard Rigging KitBlack/Gold 15' Telescoping Outrigger
