The 4 in. Open Trim finished in satin white is constructed of a steel flange with an aluminum reflector. The smooth open reflector creates an attractive finished look to your space. Integral steel flange design means light leaks are eliminated around the flange, and irregular ceiling openings are covered. Metal splay design universally blends with the surrounding decor. Easy installation featuring integrated friction springs securely mount the trim to the recessed housing and creates a snug fit against the ceiling, minimizing air leak.
