The Cable Leader 15ft NEMA L6-30P to L6-30R locking power extension cord extends a twist-lock power connection. The L6-30P plug twists and locks into a matching L6-30 -style outlet so it cannot vibrate or pull loose - ideal for equipment, power tools and gear that need a secure connection.
Built with 10 AWG, 3-conductor grounded copper wire and a SJT jacket, rated 30A/250V (300V cable). Fully molded plugs with strain relief and a true 3-wire grounded design make it safe and durable. This is an indoor-rated cord; for wet or outdoor locations, choose an SJTW outdoor-rated cord.
