Overview

The ABB 8975 4-inch set screw connector is a heavy-duty, threadless conduit fitting engineered for secure, long-lasting connections in industrial electrical installations. Manufactured by ABB - Installation Products, this connector features a durable malleable iron body that resists physical stress, corrosion, and vibration, making it ideal for demanding environments such as manufacturing plants, power generation facilities, and commercial buildings. Designed for use with rigid metal conduit (RMC) and intermediate metal conduit (IMC), the 8975 eliminates the need for threading conduit ends, streamlining installation and reducing labor time. The integrated nylon insulated throat provides critical protection for wiring by preventing insulation thinning, reducing wire pulling effort by up to 50%, and safeguarding against first-thread damage. The set screw design incorporates a captive hex head cup point screw that delivers a high-quality bond and ground continuity, resisting loosening from vibration. The connector is rated for concrete-tight applications and can carry ground fault currents up to 20,000 amps RMS, ensuring robust performance in high-fault scenarios. Available with a DURA-PLATE® finish for added corrosion resistance, the 8975 meets UL File No. E-23018 and CSA File No. 2884 standards, providing assurance of quality and safety. With dimensions of 5 15/16 inches (A) by 5 1/8 inches (B), the 8975 is sized for larger diameter conduit runs commonly found in industrial settings. Its malleable iron construction and hardened steel components ensure durability and longevity, while the nylon insulator meets and exceeds code requirements for bushings.
