Add E-Z Slides to your trailer bunks and launch your boat with ease. E-Z Slides are fabricated from a slippery composite that enables the boat to slide smoothly on and off the trailer. Ideal for launching boats on shallow ramps. E-Z Slides install directly to existing bunks with stainless mounting screws. Ideal for welded metal boats up to 4000lbs and F/G boats up to 1500lbs.
