4" 3 Ton Block

There are no better blocks available for boat lifts than the 3" or 4" ball bearing blocks. The blocks are one of the most important parts of a boat lift. Bad blocks may cause friction when the cable rolls over the shive and add lifting weight to the boat hoist. Small, underrated blocks can become the weakest part of your system. The 3" and 4" blocks are factory rated and feature ball bearings so they are virtually friction free!
