Heat-Treated 25kN Locking Connector for Industrial Fall Arrest Systems

Manufactured from high-strength heat-treated steel, this 25kN locking connector is engineered for industrial fall-arrest systems, full-body harnesses, safety lanyards, rescue equipment, and work-at-height assemblies.

The controlled heat-treatment process helps improve the steel body's tensile strength, hardness, impact resistance, and fatigue durability. This allows the connector to maintain its structural stability under repeated loading, frequent connection cycles, and demanding industrial use.

The reinforced steel construction provides dependable resistance to deformation and mechanical impact. Depending on the intended environment, available surface treatments may include zinc plating, electrophoretic coating, or other customized corrosion-resistant finishes.

For OEM safety equipment manufacturers, the connector offers:

Stable mechanical performance

Consistent dimensions across production batches

Reliable compatibility with harness and lanyard components

Custom surface finishes, markings, and packaging

Scalable production for bulk assembly requirements

With a specified minimum breaking strength of 25kN, this locking connector provides dependable load-bearing performance for professional fall-arrest and work-at-height systems.

Its reinforced body geometry is designed to guide the primary force toward the main load-bearing spine, helping reduce stress concentration around the gate when the connector is correctly positioned and loaded along its major axis.

The locking mechanism helps reduce the risk of accidental gate opening caused by movement, vibration, or contact during operation. Depending on the final product configuration, locking options may include screw-lock, twist-lock, or automatic-locking mechanisms.

Production quality can be evaluated through:

Major-axis tensile testing

Gate strength and alignment inspection

Locking-function verification

Opening and closing cycle testing

Fatigue and permanent-deformation checks

Dimensional and surface inspection

Batch identification and traceability control

Permanent 25kN markings, OEM logos, batch codes, and serial numbers can be added according to customer requirements.

The 25kN value represents the specified breaking strength and should not be interpreted as the working load limit. The appropriate safety factor and permitted working load must be determined by the equipment manufacturer according to the complete system design, intended application, applicable standard, and risk assessment.

Compliance with EN 362, ANSI Z359, or other regional standards should only be claimed when supported by product-specific testing and valid certification.
