It ships with a pancake-style bar hanger that adjusts from 18.5 inches to 26.75 inches, allowing the box to span standard joist spacing without the need for exposed framing. The adjustable bar slides into the ceiling opening and locks against the joists, keeping the box flush with the ceiling surface. Licensed electricians install this box in new construction and retrofit ceiling applications where a code-compliant, fan-rated or fixture-rated mounting point is required.\u003c\/p\u003e\n\u003cp\u003eThis ceiling box is suited for residential and light commercial installations where a surface-mounted round box is needed for a ceiling fan, chandelier, or flush-mount light fixture. The adjustable bar hanger makes it practical for retrofit work — no attic access required. The 20 cubic inch interior provides adequate fill capacity for the conductor counts typical in branch-circuit ceiling drops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 cubic inch box capacity supports standard conductor fill requirements\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter round pancake-style profile keeps the box low-profile at the ceiling\u003c\/li\u003e\n  \u003cli\u003eAdjustable bar hanger spans 18.5 inches to 26.75 inches for versatile joist spacing\u003c\/li\u003e\n  \u003cli\u003eBar hanger mounts through a ceiling cutout without requiring attic or above-ceiling access\u003c\/li\u003e\n  \u003cli\u003eDesigned for ceiling fan and light fixture mounting in branch-circuit ceiling drops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction ceiling box for residential and light commercial branch-circuit ceiling fixture and ceiling fan mounting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the NEC and applicable local codes.
