Brace kits drop through a 4 in. hole and span the joists; side-mount, pancake, and box-only formats cover direct-to-framing work.\u003c\/p\u003e\u003cp\u003eThe adjustable brace spans 16 to 24 in. joist spacing and its gripping teeth bite the framing as the bar tightens, so retrofit fans go in from below without opening the ceiling. Boxes take both 10-24 and 8-32 fixture threads per the published listing, and five knockouts with an included cable connector handle the wiring on the brace kits. Capacities run 5.9 to 21.5 cu. in. by format.
