The HBL5280C is an INSULGRIP® heavy-duty straight blade plug featuring an anchor lock for secure connections. Constructed from impact and chemical-resistant black and white nylon, it includes an integral VARI-SIZE™ cord grip that accommodates cord diameters from .230 to .720 inches (5.8 to 18.3 mm). The design incorporates powerful offsetting cord grips to prevent strain on terminals and a ribbed, beveled housing to prevent snagging. As a UL component listed device, the HBL5280C is intended for specific equipment applications rather than general use, where a secure connection is critical.
