D4 grips are designed for hauling applications where the cable is hauled to a fixed position with one eye, and then attached to that position with the other eye. They are also designed for underground mining environments where aluminium alloys are not permitted and where thimbles are needed to protect the eyes from wear and tear. They are made from durable 2070 grade galvanised wire, and are swaged with copper ferrules. They have a slimline design to reduce snagging, and all protruding wires are covered with heat shrink to protect the operators hands.
C7 grips are for general hauling or load restraint applications where a thimble is needed to protect the eye from wear and tear, typically in corrosive or marine environments. They are made from the toughest 316 grade stainless steel wire, and are swaged with a stainless steel ferrule. They have a slimline design to reduce snagging, and all protruding wires are covered with heat shrink to protect the operators hands.
