The ECM INDUSTRIES LLC 10-2H2 is a gray Hexlock multi-range screw-on wire connector sold in a 50-pack. Designed for copper-to-copper connections, it accepts wire gauge sizes from 18 AWG through 6 AWG, making it suitable for a wide range of residential and light commercial wiring tasks. The hexagon-shaped head accommodates a 5/16 inch nut driver or screw gun, allowing for fast, consistent installation without a standard screwdriver. These connectors are UL Listed and CSA certified, meeting recognized safety standards for electrical wiring work. Electricians and electrical contractors typically install these connectors during fixture wiring, panel work, junction box terminations, and general branch circuit connections.
The 10-2H2 connectors are well suited for residential wiring, light commercial electrical installations, and service work where copper-to-copper terminations are required. The multi-range design reduces the need to stock multiple connector sizes on the job, and the 50-pack quantity supports high-volume installation work. The screw-on style provides a secure mechanical connection with minimal tooling.
Designed as an OEM-style screw-on wire connector for copper-to-copper electrical terminations in residential and light commercial wiring applications where 18 AWG through 6 AWG conductors are used.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the breaker and verify the absence of voltage with a meter before making any wire connections. Use a 5/16 inch nut driver or screw gun to drive the connector onto the conductors to ensure a complete and secure termination. Do not mix copper and aluminum conductors with this connector, as it is rated for copper-to-copper connections only.
