Overview

The NSI Industries SRB-211 is a single-hole bushing designed for robust cable protection. Constructed from durable neoprene, this bushing is engineered to fit Form Size 3 applications, accommodating cable diameters ranging from .562 to .688 inches. Its primary function, as outlined by the National Electric Code (NEC) paragraph 373-6C, is to provide a smoothly rounded, insulating surface at raceway entrances, pull boxes, and junction boxes. This protects ungrounded conductors from abrasion and damage caused by sharp edges, ensuring electrical system integrity. The SRB-211 series bushings are designed for easy installation and offer a secure fit. The single-hole mounting type simplifies integration into existing electrical enclosures. While the provided catalog content details various T&B (Thomas & Betts) insulated fittings and their benefits, including reduced wire pulling effort by up to 50% and a temperature rating of 105°C, the specific certifications (U.L. Listed or CSA Certified) for the SRB-211 model are not explicitly stated in the provided snippets. However, the material (neoprene) and form factor (Form Size 3) indicate its suitability for general industrial and commercial electrical installations where conductor protection is paramount.
  • Durable neoprene construction for reliable insulation and protection.
  • Single-hole mounting for straightforward installation.
  • Form Size 3 accommodates cable diameters from .562 to .688 inches.
  • Meets NEC 373-6C requirements for conductor protection at raceway entrances.
  • Ideal for use in pull boxes, junction boxes, and conduit entries.
