provides high strength
True hex design for body and nut hex provides correct
t with socket, box, or open end wrenches resulting in
proper torquing of electrical connection
Pressure bar provides secure connection on a full range
of conductor combinations used with each connector
providing premium wire pull-out strength
Wire range-taking capability minimizes inventory
requirements, saves cost
