* – Based on I-Beam Ratings. BH-USA rates the individual blocks based on the rating of the beam that they are designed to fit. BH-USA bases this on structural aluminum I-Beams 4.03#/ 4.70# and 8.64#. Each block is individually rated, multiply this rating by the number of blocks to help determine boat size ie: 4 blocks each at 2,000 lbs lifting 8,000 lbs. combined.
