Overview

The Woodhead 36509 Dust-Tight Strain Relief is a heavy-duty, industrial-grade cable management solution designed for secure and reliable cable termination in harsh environments. This straight male strain relief features a 3/4" NPT threaded body, making it ideal for electrical enclosures, machine tools, automation systems, and manufacturing plants where dust, moisture, and mechanical stress are prevalent. The strain relief accommodates flexible cord diameters ranging from 13.21mm to 18.54mm (0.520" to 0.730"), ensuring compatibility with a wide variety of cables used in industrial applications. Constructed with a durable aluminum threaded body, zinc-plated steel nut, and galvanized steel mesh collar, the 36509 provides exceptional tensile strength with an approximate break strength of 136.08kg (300 lbs). The galvanized steel mesh construction resists wear and corrosion, while the neoprene dust seal gasket ensures IP66/IP67-rated protection against dust ingress and water immersion. This makes the strain relief suitable for NEMA 4 enclosures and hazardous locations, including Class I, Division 2; Class II, Divisions 1 and 2; and Class III, Divisions 1 and 2. The thermoplastic insulating bushing protects conductors from flexing and abrasion, preventing electrical failures and extending cable life. With a mesh length of 146mm (5.750"), this strain relief is engineered for long-term reliability in demanding industrial settings such as automotive manufacturing, food processing, and heavy machinery. Certified under UL File No. E76954 and CSA File No. LR32159, the Woodhead 36509 meets rigorous industry standards for safety and performance. Its straightforward installation process and robust construction make it a trusted choice for engineers and maintenance professionals seeking to secure critical cable connections in challenging conditions.
