RONDO 100/125

The RONDO 100/125 is a round gypsum diffuser that sits flush in a drywall ceiling or wall with no visible frame. The body is plastered and painted to match the surrounding surface, and magnets hold the convex cap so you can lift it off by hand to access the connection and balancing damper.
