Overview

The ABB TC129US Set Screw Connector (SKU: TC129US) is a zinc-plated steel solution engineered for secure EMT conduit installations in industrial and commercial environments. Designed for conduit sizes up to 3-1/2 inches, this concrete-tight connector ensures a stable, vibration-resistant connection critical for demanding applications. The set screw design provides positive holding strength, eliminating conduit movement and maintaining electrical continuity. The connector features an insulated throat, reducing wire-pulling effort by up to 50% and minimizing conductor damage during installation. Certified by U.L. (File No: E-23018) and CSA (LR-2884, LR-4484), the TC129US meets NFPA 70-1999 (ANSI) and NEMA FB1 standards, ensuring compliance with electrical codes for rigid and intermediate metal conduit systems. Its durable construction resists corrosion, making it suitable for harsh environments, including hazardous locations where general-purpose equipment is permitted (Class I, Div. 2; Class II, Div. 1 & 2; Class III, Div. 1 & 2). Ideal for electrical contractors, maintenance professionals, and industrial installers, this connector simplifies conduit threading while delivering long-term reliability. The hardened steel set screw and zinc-plated finish provide additional durability and ground continuity, ensuring a secure electrical connection.
