Adjust-A-Link chain slings offer the ultimate in flexibility. The unique and patented master control link allows for single leg, double leg and even basketed lifting. This design saves time and money! No longer is there a need to change out chain slings due to length or number of legs needed. One sling can do multiple jobs, and you can use two Adjust-A-Links on the same crane hook thus eliminating the need for expensive triple and quad leg slings. Now offered in Grade 100 in sizes 7/32 - 3/8", and Grade 80 in 1/2". The master control link is not sold separately, nor should it be used separately from the supplied alloy chain.
