GRFX139 provides a 1/2 inch tap size and a 3-1/8 inch inside depth, allowing direct conduit connections within compact control panels. This feature reduces the number of fittings and stock kept on hand, speeding up installation and enabling tighter layouts in machine enclosures. The four hubs and three plugs support multiple conductors, simplifying wiring harnesses and lowering labor time when wiring motors, sensors, and controllers in manufacturing lines. Surface mounting with Feraloy iron alloy enhances durability and corrosion resistance, delivering long service life in ordinary locations while minimizing maintenance costs. The blank back boss offers customization options for future expansions or field modifications without rework, translating to lower total cost of ownership. NEC/CEC compliance and UL listings further ensure code-conforming installations across U.S. and Canadian facilities.
