The HBL2321ST is a Twist-Lock Edge Device plug designed for 20A, 250V AC applications with 2-pole, 3-wire grounding configuration and screwless InsulGrip termination. The plug features a nylon housing and cord clamp with copper alloy blades and spring steel terminal spring clamp, accommodating #14 AWG to #8 AWG stranded copper wire only with cord diameters from 0.360" to 0.930" (9–24 mm). It withstands a minimum dielectric voltage of 3,000V and is certified for current interrupting at full rated current, with operating temperatures ranging from -40°C to +75°C maximum continuous. The screwless design eliminates the need for a torque wrench, features a strong steel spring to eliminate strand relaxation, and includes a funnel-shaped wire entry for ease of termination, making it ideal for faster installation and superior cord grip protection in industrial and commercial wiring applications.
