Overview

The NSi Industries 3503-US is a 1-1/4" steel rigid conduit set screw connector manufactured in the USA. This connector is designed for threadless rigid metal conduit and intermediate metal conduit, providing a secure connection to boxes, enclosures, or for coupling conduit ends. It features a thickwall steel body and a hardened hex head cup point screw for a high-quality bond that will not vibrate loose. The connector includes a nylon insulated throat, which meets and exceeds code requirements for bushings by preventing insulation thinning, reducing installation effort, and protecting the first thread. This set screw connector is suitable for concrete-tight applications and is capable of carrying ground fault currents up to 10,000 amps RMS for sizes up to 1-1/4". It conforms to UL 514B, CSA C22.2 No. 18, NFPA 70-1999 (ANSI), NEMA FB1, Federal Specification W-F-408, and Federal Standard H-28 (Threads). The standard finish is electro zinc plated and chromate coated. This product is listed and certified by UL (File No: E-23018) and CSA (LR-2884, LR-4484).
