DEFINITIONS
FITTING - Any functional accessory attached to a sling.
FLEMISH-ROLLED EYES - An eye splice that is constructed by opening the rope body into two parts, one having three strands
and the other having the remaining three strands and the core.
GALVANIZED - Zinc coating for corrosion resistance.
GRADE - Categorized by strength and/or type of material.
GROMMET - An endless circle or ring fabricated from one continuous length of wire rope.
HELIX/HELICAL - The shape formed by a line that curves around and along a central line forming a spiral.
HITCH - A method of rigging (attaching) a sling temporarily to a load or object for the purpose of lifting.
HITCH, BASKET - Method of sling loading where the sling is passed under the load with both ends, end attachments(eyes) on the hook, or single master link.
HITCH, CHOKER - Method of sling loading where the sling is passed around the load through one end attachment or eye and is suspended by the other.

KINK - A unique deformation of a wire rope caused by a loop being pulled down tight. It represents irreparable damage and indeterminate loss of strength in the wire rope.
LAY - The direction of a strand or wire helix (as it pertains to wire rope).
LAY LENGTH - The distance in which a strand makes one complete helical revolution around the wire rope core.
LOAD - The object being lifted or lowered.
MASTER LINK - Forged or welded steel link used to support all members (legs) of a sling.
MECHANICAL COUPLING LINK - A non-welded, mechanically closed link used primarily to attach  ttings to alloy steel chain.
