Double-locked cable glands provide an extra layer of security for cables in electrical or electronic installations. They are designed with two independent locking mechanisms to ensure a reliable and secure connection. These two locking mechanisms typically consist of an inner lock and an outer lock that work together to provide enhanced cable retention and sealing.

Internal locks are designed to clamp and secure the cable directly, usually through the use of serrations or teeth that bite into the cable insulation. This inner lock prevents the cable from being pulled or loosened from the cable gland, even when subjected to vibration or strain.

An outer lock, on the other hand, is a separate mechanism used to secure a cable gland to an enclosure or panel. It usually involves a gland nut or other type of fastening mechanism that secures the gland to the housing, providing a reliable and secure connection. The outer lock also helps ensure that the cable gland is properly sealed to prevent the ingress of dust, moisture, or other contaminants.

The combination of inner and outer locks in the double lock cable gland provides increased protection against pulling out cables, loosening, or the ingress of hazardous substances. This makes them suitable for applications requiring high reliability, safety, and sealing performance, such as industrial environments, outdoor installations, or critical systems.

How does the Double Lock Cable Gland work?

Double Lock Cable Gland is used to secure cable bundles and prevent accidental contact. Glands consist of a body and a cover that are locked together using a series of locks and latches. This makes the gland very tamper-resistant and very difficult to remove without the proper tools.

Double Lock Cable Glands are designed to provide strain relief, environmental protection, and grounding for cables or wires, preventing them from being pulled out, while also sealing entry points to prevent dust, dirt, moisture, or other contaminants from entering the enclosure.

Double Lock Cable Gland is typically used in applications requiring reliable cable retention, environmental protection and grounding such as electrical panels, control cabinets, junction boxes, motor enclosures and outdoor installations.

What are the benefits of using a Double Lock Cable Gland?

Double-lock cable glands have become the first choice for industrial and outdoor applications requiring a strong cable management and sealing solution.

There are several advantages to using Double Lock Cable Gland in various applications:

Enhanced Cable Retention: The double locking mechanism of the double lock cable gland provides superior cable retention compared to single lock cable glands.

Reliable Environmental Protection: The double lock cable gland is designed to provide an effective seal that prevents dust, dirt, moisture, and other contaminants from entering the housing through the cable gland. A ferrule or gasket combined with a dual locknut mechanism creates a tight seal that helps maintain the integrity of the enclosure and protects internal components from environmental hazards.

Improved Strain Relief: The Double Lock Cable Gland’s jaws relieve the strain by firmly gripping the cable or wire, reducing the risk of damage or breakage due to tension, bending or pulling.

Enhanced Security: Double Lock Cable Gland also increases security by grounding cables or wires passing through the enclosure.
