Molded nylon encases 12 pairs of connectors that use screw compression to secure wires without use of lugs. Ideal for electronic installations. Brass barrels capture wires and are held in place with a stainless steel "finger" compressed by a screw. The screw does not make contact with the wires, protecting the copper strands from cuts and breakage - meets ABYC standards. Strips are easily cut to meet requirements.
