Using the Access Lighting ModPLUS 12-inch Trim is easy. First, make sure you have the right model, 20832 or 20838. Then, simply attach the trim to your lighting fixture. Since the lamp is not included, you'll need to buy one separately. When cleaning, use a soft, dry cloth to avoid scratching the steel surface. Keep it away from harsh chemicals as they may damage the finish. For long - term use, check the connection regularly to ensure it stays secure. If you notice any issues, contact Access Lighting's customer service.
