Overview

The Woodhead MAX-LOC® Strain Relief Cord-Sealing Grip (SKU: 5538M) is a rugged industrial-grade cable management solution designed for cables with diameters between 12.70mm and 15.88mm (.500" to .625"). Featuring a 3/4" NPT straight male thread, this grip provides a secure, liquid-tight seal for electrical enclosures, control panels, and machinery in demanding environments. The core component is a single-weave galvanized stainless steel mesh collar that delivers exceptional pull-out resistance and abrasion protection, while the insulated thermoplastic bushing safeguards conductors from bending stress and environmental contaminants. Constructed with a zinc-plated steel nut and aluminum threaded body, the 5538M resists corrosion and mechanical impact, making it suitable for both indoor and outdoor industrial applications. The integrated neoprene dust seal gasket ensures IP66/NEMA 4P compliance when paired with the correct NPT-sized O-ring, preventing moisture, dust, and chemical ingress. Certified to UL File No. E76954 and CSA File No. LR32159, this grip meets stringent safety standards for hazardous locations including Class I, Division 2; Class II, Divisions 1 & 2; and Class III, Divisions 1 & 2. Installation requires no specialized tools—simply thread the grip into the enclosure, insert the cable, and tighten the compression nut to secure the mesh collar around the jacket. The half-double/half-single weave mesh design accommodates cable diameters from .500" to .625" without stripping, reducing inventory complexity. Ideal for automotive, aerospace, energy, and industrial automation systems, the 5538M minimizes downtime by protecting critical connections from vibration, thermal cycling, and environmental exposure. Backed by Woodhead’s decades of connectivity expertise, this strain relief grip delivers proven reliability in harsh operating conditions.
