The problem with many rigging hooks is that they are large, and their large profile makes them impossible to fit into tight spaces. These Alloy J Hooks from M&W were designed to fill that void. They are rated for lifting and they have a very skinny profile, making them great lifting engines and transformers. They are manufactured to meet ASME B30.20 and OSHA standards. They are durable and made for rugged use in both warehouse and jobsite environments. Made in U.S.A.
