The ECM INDUSTRIES LLC 19-086 is a red Wing-Gard screw-on wire connector designed for copper-to-copper electrical connections. Rated at 600 volts, it accommodates wire combinations ranging from 18 AWG to 10 AWG, making it suitable for a wide range of low-voltage and line-voltage wiring tasks. Each pack contains six connectors. The connector features a twist-on screw design that creates a secure, insulated termination without requiring additional tools beyond a steady hand. UL Listed and CSA Approved, this connector meets widely accepted safety standards for electrical installations in residential and light commercial applications.
This wire connector is used in electrical rough-in and service work across HVAC, plumbing controls, and general electrical trades. Technicians reach for this connector when splicing control wiring, thermostat leads, or branch circuit conductors within the rated AWG range. The red color coding helps identify wire gauge groupings at a glance during inspection or service calls. The carded packaging keeps connectors organized on the job site or in a service vehicle.
Designed for copper-to-copper wire splices on 18 AWG to 10 AWG wire combinations in residential and light commercial electrical systems rated up to 600 volts.
Wire connectors of this type are installed by licensed electricians or qualified trade technicians following NEC guidelines. Disconnect and lock out power to the circuit before making or breaking any wire connections. Strip conductors to the appropriate length, twist wires together if required by the connector design, then thread the connector clockwise until firmly seated with no bare conductor exposed. Do not exceed the rated AWG range or voltage rating of the connector.
