TERMINATOR TM-RY-17D Red and Yellow 17000-Piece Bulk Drum of Premium Wire Connectors form secure connections on solid or stranded wires in the 18-8 AWG range. The bicolored design fits a wider range of wires using an expanding quick-bite spring made from zinc-plated steel that grips in any pigtail application, including junctions, splits, outlets and switches. The flexible skirt covers over-strips and protects against wire exposure or shorts by molding into tight spaces. Additionally, the swept-back wing design is ergonomic when applying torque to save your fingers after a long day of making splices and buttoning up junction boxes.
