Natural Light 18 Inch Tubular Skylight Trim Ring
Both of the arc-shaped diffusers are made of durable acrylic. The soft white diffuser's surface is smooth and evenly spreads a softer tone of light. The prismatic diffuser's surface contains several small prisms to help spread the light evenly. They snap easily into the trim ring. For use with Natural Light's 21" Skylight.
This product does not include the diffuser it is the trim ring only.
