The Dual Pillow Block Pipe Support with pillow blocks attached is the ultimate support for any center mount boat lift. This low-profile dock mounting pipe support will mount to virtually any overhead wood beam with the adjustable brackets. They have two 2-7/16” cast iron ball bearing pillow blocks, eliminating the friction that can be created when using other pipe supports with standard sleeves. Your lift will operate smoothly and quietly for years. It will give the pipe needed support on both sides of the cable, greatly reducing the chance of the unit getting into a bind. Add an optional cable winder and make lifting your boat smooth and easy. Installation: Center Pipe Lift only. Mounting hardware not included.
