Washdown Turn-Lock Extension Cords

Protect against washdowns and high vibration that could disconnect cords, typical on assembly lines and heavy machinery. To maintain their washdown rating during use, attach these cords to washdown-rated connectors (not included), which have multi-ring seals to keep water out. The thick rubber jacket on these cords resists water, chemicals, weather, and abrasion. The attached covers protect unused sockets from debris, moisture, corrosion, and physical damage.
