Overview
The Allied Moulded Products 9351-NKFR is a 4 in. diameter round fiberglass ceiling electrical box from the fiberglassBOX™ series, engineered for new work residential and light commercial construction. At 2-7/16 in. deep with 22.5 cubic inches of capacity, this box supports both fan and fixture loads — rated for 35 lbs. fan support and 50 lbs. fixture support. The thermoset fiberglass reinforced polyester BMC construction resists distortion at high temperatures and remains shatter-resistant in low-temperature conditions, making it a durable choice across a wide range of job-site environments.
Factory-installed Speed “K” PVC clamps accept nonmetallic sheathed (NM) cable quickly and securely. Fetter ring nails are included for fast nail-on mounting to wood framing. Machine-tapped fixture holes ensure positive engagement with fan and fixture hardware. Certified to ANSI/UL 514C (File No. E30594) and carries a 2-hour fire resistance classification for both wall and ceiling assemblies per ANSI/UL 263 (File No. CEYY.R9379). Manufactured in the United States.
