This five-inch IC rated housing is suitable for new construction in residential and commercial applications and for direct contact with insulation. Integral thermal guards protect against improper lamping and misuse of insulation materials with lamp wattage ratings and apertures based off trim selection. The airtight housing limits the exchange of air between ceiling plenum and heated/cooled areas. The housing adjusts from 1/2" to 1 1/2" to accommodate ceiling thickness and its 7 1/2" height allows it to be used in 2"x8" joist construction.Input Voltage: 120VCertifications: cULus Damp Airtight ICAirtight housing limits exchange of air between ceiling plenum and heated/cooled areasTransformer includes thermal protector guards against lamping and misuse of insulation materials7 1/2" height allows use in 2"x8" joist construction.HousingAluminum construction provides greater heat dissipationWashington State Energy Code approved to meet restricted airflow requirementsPlaster FrameHousing is secured to plaster frame with screws and can be removed for access to junction box.Housing adjusts from 1/2" to 1 1/2" to accommodate ceiling thickness.Junction BoxListed for through branch circuit wiring and includes several 3/4" knockouts.Four pry-outs with integral strain relief simplify Romex installation.Supplied with three push-in wire connectors.Hanger Bars-Heavy-gauge NICOR captive hanger bars provide greater stability, allowing housing to be positioned at any point within a 24" joist span, then locked in place with set screws.Unique hanger bar lip design helps align can to joist.Four double-headed captivBars can be repositioned 90" on plaster frame without tools.Bars fit onto T-bar spine for quick alignment and can be permanently secured.Score lines allow bars to be shortened without tools to accommodate a 12" joist span.
