Stonco VP21 Roughlyte Pendant Mount Vaportight Adapter

Stonco VP21 Roughlyte Pendant Mount Vaportight Adapter is a pendant-mount accessory in the Roughlyte Vaportight family, designed to attach Roughlyte pendant fixtures to a suspension system and provide moisture‑resistant performance for damp or exterior locations. This adapter is not a complete fixture; it ships separately from the lamp, and, as documented by Stonco, VP Roughlyte fixtures are intended for pendant installations and do not include a stem, so the VP21 functions as the mounting interface to receive a pendant stem or suspending hardware. Within the Roughlyte pendant-mount lineup, variants such as VP21K are described as a 200-watt glass-globe pendant assembly, and catalogs show configurations where the VP21 base adapter is paired with a glass globe to form a ready-to-install, moisture-protected pendant luminaire suitable for exterior or damp environments.
