Overview

The Woodhead 36504 Dust-Tight Strain Relief Grip (SKU: 36504) is a high-performance cable entry and strain relief solution designed for demanding industrial environments. This straight male fitting features a 1/2" NPT threaded body, ensuring secure installation into compatible electrical enclosures, junction boxes, or equipment panels. The strain relief is engineered to accommodate flexible cable diameters ranging from 7.62mm to 10.92mm (.300" to .430"), providing a tight grip that prevents cable movement and reduces stress on internal electrical connections. Constructed with a galvanized steel mesh insert, the 36504 delivers robust mechanical strength with an approximate break strength of 136.08kg (300 lbs), ensuring reliable cable retention even under tension. The aluminum threaded body offers corrosion resistance while maintaining a lightweight profile, and the zinc-plated steel nut enhances durability in harsh conditions. A neoprene dust seal gasket is integrated into the design to create a tight seal, effectively blocking dust, dirt, and other contaminants from entering the enclosure. This dust-tight feature makes the 36504 ideal for use in manufacturing facilities, machine tools, bus drops, and other industrial settings where environmental protection is critical. The 36504 is certified to UL File No. E76954 and CSA File No. LR32159, confirming compliance with North American safety standards for electrical components. Its single-weave mesh design ensures consistent gripping force across the specified cable diameter range, minimizing the risk of cable pull-out or damage. Whether used in new installations or retrofits, this strain relief grip provides a reliable solution for securing cables while maintaining environmental integrity in industrial applications.
