Eaton GRF139 Condulet - Copper-free aluminum, NEC/CEC
Part Number: GRF139
Quick Summary
GRF139 is a Condulet tapped outlet box for surface mount installations in non-hazardous industrial panels. Engineers often struggle to meet NEC/CEC while delivering reliable, corrosion-resistant enclosures that simplify wiring in tight spaces. This model uses copper-free aluminum and a 1/2" tap size with 4 hubs and 3 plugs, supporting quick field connections and neat terminations. It is certified for Ordinary/Non-Hazardous Locations and UL-listed for both US and Canada, reinforcing safety and traceability. By standardizing on GRF139, maintenance costs are reduced and panel assembly timelines shorten, delivering measurable business value for control-system projects and ongoing operations.
