Vintage Brown Ceramic Electrical Insulator PP5201 USA

Vintage dark brown glazed ceramic electrical insulator marked “PP5201” and “U.S.A.” on the top.

Measuring approximately 3 inches × 3 inches, this compact utility insulator has a deep brown glaze and substantial ceramic construction. The visible alphanumeric marking adds interest for collectors of vintage electrical equipment and industrial hardware, even though no manufacturer name is visible.

Originally made as functional electrical hardware, it also works well as a small sculptural display piece among vintage tools, mechanical objects, books, or other industrial finds.
