LIBO's 4" housing is the fixture for you if you're looking for a larger aperture (4 inches) for installation in non-insulated ceilings. Like most of Libo's 5~6" recessed down lighting fixtures, the Libo's 4" housing is designed for ease of installation and flexibility across a variety of materials and situations. The housing include pre-installed spring in special housings that ensure smooth, straight penetration, whether you're working with laminated composites, engineered I-joists, open-web joist plates, or even frozen lumber. The automatic leveling flanges allow you to hold the housing securely in place with one hand while driving nails with the other.
Available with a variety of trim options (sold separately), some of which allow you to use 4" fixture. Note that, while this is not an IC-rated fixture, insulation may be placed around it as long as a 4-inch space is maintained around the housing. ETL damp-location and feed-through rated; ETL certified; IP rated.
