      • Utility Lift On Dock

      Comments about Ronstan Series 29 Utility Block, Double/becket, 990lb. Swl, 1.8oz.:

      Works great to give me an advantage to line up a slide on a dock pilling. The slide allows the boat to move up and down with tides. Slide assembly is heavy and I rigged two of these blocks with light line making is very easy to set the slide two the right position when I dock a 35' sailboat. Works great for my application, and would be a good product for small boats

      Service and delivery comments:

      Items were delivered to my address in Mo. Even though I entered a delivery address in FL. My billing address was in Mo. Product arrived in good condition and looks nice

            Comments about Series 29 Utility Blocks:

            When you want something to last and not corrode or rust, go marine. Works great for lifting the cover off my spa and just nothing available at the local hardware store.
