Whirlwind HBL4715C Hubbell Twist-Lock L5-15R Flanged Receptacle

The HBL4715C is the Hubbell twist-lock AC device Whirlwind stocks alongside its own distro and cable work: NEMA L5-15R, 15 A, 250 V. Buying the connector from the same place as the cable is how a distro build stays on one purchase order and one lead time.

It is a flanged receptacle, so it terminates the female end of the run. Hubbell's Insulgrip bodies are nylon, which is what stands up to the impact and the chemicals a touring rack meets, and the cord grip clamps the jacket rather than letting the strain reach the terminals.
