Vintage Neon Sign Glass Insulator Housing #200, 7500V, Set of 4.

Rare matched set of four vintage neon sign glass insulator housings marked “#200” and “7500V.” These industrial electrical components feature thick clear molded glass bodies with internal spiral resistance elements and heavy threaded metal terminals.

Originally used in high-voltage neon sign or commercial electrical applications, these pieces have an outstanding industrial aesthetic and display beautifully as sculptural decor objects, steampunk accents, or collectible electrical artifacts.

The exposed internal coil construction combined with the embossed industrial markings gives the set a strong early electrical engineering and laboratory appearance.

Condition is very good vintage condition overall. All four retain their original internal internal wire assemblies and metal fittings. Glass remains clear with expected age-related wear, small surface marks, and oxidation/patina to the metal components. No major cracks observed.

An increasingly difficult-to-find matching set, especially in this quantity and condition.
