The Crosby A-378 Sorting Hooks are popular with those that handle steel plates and / or cylinders. They are made from forged alloy steel and come in two styles as shown below. Available with or without a handle--the handle is a safety feature that helps to keep worker hands away from potential pinch points, and generally makes for easier handling.
Please note the Working Load Limit (WLL) of these hooks varies greatly depending on where the hook is loaded. Below, the WLL of 2 Tons is for when the hook is loaded on the tip. If the hook is loaded vertically, at the bottom, then the WLL increases significantly up to 7-1/2 Tons.
