Rittal HD 2410.021 stainless steel cable gland set, pack of 5, M20x1.5 compatible

Rittal HD 2410.021 stainless steel cable gland set, pack of 5, M20x1.5 compatible provides five metallic cable entry fittings designed for secure and durable cable routing into enclosures, control cabinets and outdoor housings. Made from stainless steel, each gland resists corrosion and mechanical wear while matching M20x1.5 thread dimensions for standard metric panel holes. The set includes lock nuts and features a compact profile that saves panel space compared with larger gland designs.

Advantages

The stainless steel construction ensures high corrosion resistance, making the glands suitable for harsh indoor and outdoor environments. The pack of five supplies multiple entry points for small- to medium-sized installations while the included lock nuts simplify assembly and provide firm mechanical fixation. The compact design reduces protrusion from panels, allowing neater installations and easier placement in confined spaces.

Suitable for

• Industrial electrical installations and control cabinets
• Outdoor enclosures and weather-exposed panels
• Signal, power and control cable entry where metallic glands are required
• Applications requiring M20x1.5 threaded panel entries

When it may not be suitable

These stainless steel glands are intended for M20x1.5 threaded holes; they will not fit enclosures or panels with different thread sizes and require matching tap or knockout preparation. They are metal fittings and do not provide the same insulation properties as plastic glands, so additional insulation or protective measures may be needed where electrical isolation is critical.

Key specifications

• Material: stainless steel (metallic corrosion-resistant construction)
• Quantity: pack of 5 pieces
• Thread size: compatible with M20 x 1.5 metric threads
• Design: compact profile with included lock nuts for panel fixation

How to use

Prepare the enclosure or panel with an M20x1.5 threaded hole or an appropriately tapped hole. Insert the gland body through the panel from the outside and secure it from the inside using the supplied lock nut, tightening to a firm but not excessive torque to avoid thread damage. Route the cable through the gland and, if applicable, apply any required sealing or strain-relief components. Verify mechanical fixation and, if necessary, use additional washers or torque-limiting tools to meet installation guidelines.

What to consider before purchase

• Confirm panel hole diameter and thread type correspond to M20x1.5 metric specification
• Assess cable diameters intended for use to ensure compatibility with the gland internal diameter
• Determine environmental requirements (corrosion, UV, salt spray) to verify stainless steel is appropriate
• Check if additional sealing inserts or grommets are needed for IP-rating or vibration resistance

Usage recommendations

Use appropriate torque settings when tightening lock nuts to avoid deformation of threads. For outdoor or marine installations, select stainless steel grades and sealing inserts suitable for the specific environment and perform periodic inspections to ensure long-term integrity.
