RACO introduces an expanded line of electrical boxes designed for plenum applications. These products provide additional options for above-ceiling installations.
RACO's plenum rated boxes are used in above-ceiling applications where air-tight enclosures are required, for use in air returns or required by code. 15 models are offered, including three different box styles-4" square, 4-11/16" square and 4" octagon. Two models feature shallow 1-1/2" depths.
Knockouts on these plenum boxes are airtight. The 4" square models provide a variety of ½" and ¾" knockout options. The 4" octagon models offer ½ and ¾" knockouts. The 4-11/16" square models offer knockouts that range from ½" to 1-1/4."
These cULus Listed boxes are constructed of drawn steel. To maintain the plenum seal, no ground screw holes are provided. Also available are PVC foam gasketed flat blank covers and extension rings for the 4" and 4-11/16" square boxes.
