  • HEAVY DUTY 30 AMP ADAPTER: Premium 10 gauge (10/3) STW copper wire converts a standard RV plug (NEMA TT-30P) to a Twist-Lock connector (NEMA L5-30R). Rated for 125 Volts and 3750 Watts. Perfect for connecting generators or transfer switches with a secure, locking connection.
  • COMPACT PLUG WITH SIDE WINGS: Unlike bulky handle plugs that prevent power box lids from closing, our low-profile TT-30P plug fits perfectly inside standard outlets. The ergonomic side wings design provides a non-slip ridge, allowing for easy unplugging without the bulk.
  • SECURE TWIST-LOCK FEMALE: Features a NEMA L5-30R locking connector on the female end. Simply insert and twist to lock, ensuring the cord stays connected to your inlet box or equipment even during vibration or accidental pulls.
  • ALL-WEATHER FLEXIBILITY: The durable yellow STW jacket is highly visible and water-resistant. It remains flexible in extreme temperatures (-40°F to 221°F), resisting abrasion, moisture, and sunlight for long-term outdoor use.
  • ETL LISTED SAFETY: Full ETL certification ensures safety compliance. Includes a bonus adjustable storage strap to keep the extension cord organized.
