Even beefier than the standard HR-125UNC line of hoist rings, Crosby makes the HR-1000UNC series specifically for heavy lifts. You still get the full 180º pivot and 360º swivel action, but the bail is made from forged alloy steel and reinforced with a cross member. The bail also has a more generous throat opening than the common HR-125UNC hoist ring. The top washer has the Working Load Limit and recommended torque value permanently stamped into it, and is color-coded red to indicate metric threads. All hoist rings are proof-tested to 2-1/2 times the Working Load Limit.
