Singing Rock D Steel Connector Screw K4080

Extremely strong D-shaped steel carabiner for work at height

The D STEEL CONNECTOR Screw K4080 is a heavy-duty steel carabiner designed for professional work at height, fall protection, anchoring and industrial applications. Its D-shaped construction optimises force distribution along the major axis and provides high stability under load.

The carabiner has a 50 kN major-axis strength and a 25 mm gate opening, providing ample space for connecting compatible equipment. It features a screw-lock mechanism for manual locking and a Keylock system that helps reduce the risk of the carabiner nose catching on loops or other equipment.

The durable steel construction makes the carabiner suitable for demanding professional environments. The K4080 is available in a zinc-plated version or in black with ED coating. The black surface treatment is designed to provide long-term durability.

A unique production number makes the carabiner easy to identify and record during periodic inspections.

The K4080 combines high strength, durable steel construction and a practical screw-lock mechanism in a D-shaped carabiner designed for professional applications where reliable connection equipment is required.
