Overview

The Woodhead MAX-LOC® Strain Relief Cord-Sealing Grip (SKU: 5540) is a rugged, liquid-tight strain relief solution engineered for industrial electrical cable management. Designed for 3/4" NPT straight male installations, this grip accommodates cable diameters from 14.27mm to 17.45mm (0.562" to 0.687"), making it ideal for enclosures, push-button stations, and junction boxes. The unit features a corrosion-resistant nylon body with a zinc-plated steel compression nut, ensuring long-term durability in harsh environments. Its rubber grommet provides a NEMA 6P-rated liquid-tight seal when paired with the correct O-ring and locknut, protecting internal components from moisture, contaminants, and mechanical stress. The grommet is color-coded (gray for this size) for easy identification and is formulated to resist a wide temperature range and common industrial chemicals. The MAX-LOC® series is UL File No. E76954 and CSA File No. LR32159 certified, offering Type 3R protection without an O-ring and Type 6P with an O-ring/locknut. The half-double weave, half-single weave mesh construction provides moderate strength and flexibility while maintaining non-conductivity. This strain relief grip is manufactured in the US by Woodhead, a trusted name in industrial electrical components.
