#300 Glass Neon Housing

The "Spring Type" #300 neon electrode housing features an open-back design commonly used in outdoor signs, especially in areas with high insect activity and rain (ie: Seattle). Since illuminated neon tubes attract flying insects, the open-back construction allows bugs that enter the housing to fall into the sign cabinet instead of accumulating inside the housing itself. This helps prevent blockages that could retain moisture during rain, potentially creating an electrical arcing hazard.

The “spring type” #300 housing features an internal spring that carries the high voltage from the neon transformer. A neon electrode fitted with a brass button or brass cap is inserted into the housing, where it makes contact with the spring to receive power. This spring-loaded design also makes neon tube maintenance and replacement quicker and easier.

The #300 housing uses a unique mounting hole size that differs from other neon electrode housings. When restoring a vintage sign with existing pre-punched mounting holes sized for the #300 housings, you will either need to use actual #300 housings or use our Neon Housing Collars. Our Neon Housing Collars allow the more common #200 housings to be mounted into the #300 mounting holes. Refer to our Housing Accessories page to order the Neon Housing Collars.
