Four Bross NC4/LED 4 inch LED recessed housings are specially designed for quick and easy installation during new construction projects. The low can height allows for installation in tight ceilings with 2 in. x 6 in. joist construction. Each pot light comes with a dedicated LED push-in connector system that provides high efficacy code compliance when used with qualified LED trims equipped with same connector. The airtight design helps reduce heating and cooling costs by minimizing air flow through the ceiling. These recessed cans include adjustable hanger bars, are IC rated and pre-wired for easy installation.
