Eaton PFTA4 4Q102AR Ruff-IN Assembly - NEC/CEC
Part Number: PFTA4 4Q102AR
Quick Summary
Eaton Crouse-Hinds Ruff-IN assembly provides rugged, ready-to-install dual-gang boxes for industrial enclosures. Field-fit tolerances, knockout configurations, and mounting alignment frequently slow projects; this solution mitigates those risks with a welded construction, adjustable two-gang mud ring, and built-in clamps. It aligns with NEC/CEC standards, carries a NEMA 1 rating, and is suitable for ordinary/non-hazardous locations, offering code-compliant performance in challenging environments. By supporting backside mounting for 2-1/2" through 6" studs and 16"–24" stud spacing, it simplifies installation, reduces site labor, and improves long-term reliability. With MC-conduit integration and solid ground, you gain consistency and faster deployment, translating to lower total installed cost.

FAQs
The PFTA4 4Q102AR supports 16"–24" stud spacing and offers backside support for 2-1/2"–6" studs, enabling flexible mounting on a wide range of racking and panel configurations. Its welded construction and standardized knockouts simplify alignment, reducing on-site adjustments and rework while improving overall enclosure rigidity and grounding continuity.
In non-hazardous environments, the PFTA4 delivers faster installs through a built-in adjustable mud ring, two clamps, and a solid ground wire. Its compact 4" box with multiple knockouts minimizes field modifications, while its MC-conduit integration protects conductors and reduces hardware count, translating to lower labor costs and shorter commissioning times.
The assembly includes three bottom, three side, and three end knockouts plus two cable pryouts, with an integral MC connector for conduit management. These features provide versatile wiring paths, simplify routing in tight spaces, and support clean, code-compliant terminations in dual-gang configurations for control panels and junctions.
The PFTA4 4Q102AR is designed to NEC/CEC compliance and carries a NEMA 1 rating, suitable for Ordinary/Non-Hazardous Locations. This combination ensures electrical safety, reliable enclosure protection, and broad regulatory compatibility across North American industrial installations.
Using Ruff-IN assemblies reduces on-site assembly time with welded construction, built-in clamps, and an adjustable mud ring, minimizing field fabrication and rework. The standardized dimensions and knockouts streamline wiring runs and terminations, enhancing first-pass quality and accelerating project timelines, which collectively lower total installed cost and improve return on investment.
