Appleton BL-150 Locknut

Appleton BL-150 Locknut is a steel, 1-1/2 inch trade-size conduit locknut from Appleton’s Conduit and IMC locknut line, designed for use with IMC and rigid conduit fittings. The Tiger Grip-style nut fastens securely to enclosures to resist loosening from vibration, with an external width of about 2.38 inches and a height of roughly 0.19 inches. It carries UL 514B and CSA listings, with UL file number E14814, and a NEMA FB1 rating, indicating suitability for standard electrical installations. Grounding is not provided by this locknut, making it a non-grounding component in IMC/rigid conduit assemblies. Weighing approximately 0.1 lb, the BL-150 is intended to complement Appleton’s IMC and rigid conduit fittings for durable, compliant mechanical retention in commercial and industrial electrical installations.
