Duraline Product Range: Industrial-Grade Power, Lighting, and Distribution Solutions Built for the Toughest Environments

Since 1946, Duraline has been a leading American manufacturer of heavy-duty electrical power connectors, temporary lighting systems, high-current distribution equipment, and custom-engineered solutions designed for some of the harshest environments on earth. From naval shipyards and refineries to construction sites, film studios, mining operations, and emergency response zones, Duraline products are engineered to deliver absolute reliability where failure is not an option.

This comprehensive overview explores the full range of products available on JBN-Duraline.com, with a focus on performance, industrial suitability, and key applications — all while optimizing for strong search visibility in the electrical, marine, and temporary power sectors.

American-Made Quality Since 1946

Duraline is a division of J.B. Nottingham Co., Inc., a U.S. manufacturer headquartered in DeLand, Florida. Every connector, cable assembly, distribution panel, and molded component is made in-house with complete quality control — from machining brass contacts to molding rubber over cables.

Industries rely on Duraline because its products consistently survive conditions that destroy traditional electrical equipment, including:

• Constant vibration
• Water and salt exposure
• High-pressure wash-down
• Abrasion and rough handling
• Mud, dust, grease, and corrosive chemicals
• Heavy current loads under continuous duty

This heritage of reliability sets the foundation for everything in the Duraline catalog.

Single-Pole Cam-Type Connectors: High-Current Solutions for Industrial and Marine Use

One of Duraline’s flagship categories, the Single-Pole Cam-Type Connector Series, includes the E1017, E1022, E1023, X-Power, and field-attachable options. These connectors are the backbone of shipyards, generator hookups, entertainment venues, temporary power grids, and industrial facilities.
