Eaton PFTWFA 4Q10275 Ruff-IN Assembly - NEMA 1, NEC/CEC
Part Number: PFTWFA 4Q10275
Quick Summary
The Eaton Crouse-Hinds Ruff-IN assembly is a rugged 4" two-gang box system designed for industrial enclosures. Engineers often contend with misalignment, field fabrication, and non-code compliant installs in harsh environments. This rugged Ruff-IN is NEC/CEC compliant, NEMA 1 rated, and UL-listed for US and Canada. Its wide flange telescoping bracket supports 14-1/2" to 25" stud spacing and features built-in clamps for fast, secure mounting. In practice, it delivers faster installation, reduces field rework, and ensures reliable grounding in ordinary or non-hazardous locations, while providing compatibility with 14-1/2"–25" stud layouts and a 4" box footprint for streamlined control-panel wiring.
