The returned loop is fabricated by forming a loop at the

end of the rope, sliding one or more metal sleeves over

the short end of the loop eye and pressing these sleeves

to secure the end of the rope to the sling body.  This

makes an economical sling and in most cases one that will

give satisfactory service.  A drawback to this type of sling

is that the lifting capacity of the sling depends 100% upon

the integrity of the pressed or swaged joint.  Should the

metal sleeves(s) fail, the entire eye will also fail.
