This round diffuser is a nice replacement for those used on most 1969 to 1971 Airstreams.

It is 7-5/8" diameter at the base. Check your fixture to confirm the measurement before ordering.

The original shade had small vent holes under the knob. Ours comes without the vent holes because we assume most trailer owners have converted to much cooler LED bulbs to cut energy consumption by 80%. If you want to continue to use incandescent bulbs, you may choose to drill the vents. We have provided dimple markings on the diffuser to guide you if you decide to drill.

Made of durable polycarbonate.
