Galvanized Metal Lighting Lids for Mason, Ball, Canning Jars (3 Pack, Regular Mouth) - Mason Jar Lifestyle

• This lid has a 4cm (1.57″) hole in the middle, which fits a variety of pendant, vanity, sconces, and other light fixtures. They generally have a plastic nut that screws on and holds the glass shade in place – view the second photo to see if your light fixture is compatible. Not every light fixture uses this standard size - measure first! Measure the Mason jar you plan to use - a regular mouth jar is 2 3/8" internal diameter and a wide mouth Mason jar is 3" internal diameter. Ventilated for heat dispersion and air flow. Use them with a normal jar and a low wattage LED bulb, or use one of our open bottom jars with any type of bulb. Be sure your bulb fits into the jar. These lids are made of galvanized metal, so it is possible they could rust in humid locations, but they do have an anti-rust coating. 💕 COLORADO BASED COMPANY WITH TOP NOTCH CUSTOMER SERVICE: Buy with confidence from this family run, Colorado based business which offers exceptional customer service from our U.S. based Mason jar experts!
