These durable hooks are not only very strong--being made of Grade 120--but safe as well. They feature a beefy self-closing latch that slams shut as soon as a load is applied. These latches are stronger and last much longer than traditional flipper latches. You also get a more generous throat opening, meaning you can rig with this hook more easily than with standard sling hooks. Powder-coated blue for corrosion protection. Safety factor of 4:1.
