Carabiner with eyelet | A4
A stainless steel carabiner with eyelet is a strong and functional connector that combines quick handling with high security. The eyelet at the rear makes it easy to attach the carabiner permanently to ropes, cables, or other equipment, while the spring-loaded gate allows for quick one-handed connection.
AREA OF APPLICATION
The robust construction makes this carabiner particularly suitable for marine environments, industrial applications, construction, and recreational use where reliable and flexible fastening is required.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is the advantage of an integrated eyelet at the rear of the carabiner?
The eyelet (fixed eye) provides two crucial functional advantages compared to an open standard carabiner:
-
Permanent and secure attachment: The rope, cable, or strap is shackled or tied directly into the eyelet. This prevents the carabiner from sliding along the line or accidentally losing contact with the line when detached.
-
Correct load direction: The eyelet directs the force so that the load is always placed along the length of the carabiner (straight pull), which prevents cross-loading that could otherwise reduce the actual strength of the carabiner.
Why is acid-proof stainless steel A4 (AISI 316) standard for this type of carabiner?
A4 steel (1.4401 / AISI 316) is the superior material choice for chlorinated, marine, and harsh industrial environments:
-
Maximum corrosion protection: The molybdenum alloy in the A4 steel provides complete protection against pitting and crevice corrosion from saltwater, spray, exhaust gases, and harsh cleaning agents.
-
Durable spring closure: The internal spring and retaining pin are made of corrosion-resistant material to ensure the gate closes quickly and reliably even after long-term exposure to the elements.
-
No discoloration: Leaves no rust stains on sails, ropes, decks, or covers.
How do you choose the right size and how should the carabiner be used?
-
Adaptation to rope/material thickness: Select the carabiner size based on the diameter of the rope to be attached to the eyelet as well as the thickness (d) of the fitting or eye the gate will be connected to.
-
Quick handling: The spring-loaded gate can easily be opened with the thumb for quick one-handed operation, making it perfect for canvas fasteners, fender lines, halyards, safety lines, and temporary rigging.
-
Note on safety markings: Standard carabiners of this type are intended for rigging, mooring components, and load securing — they are not approved as personal protective equipment (PPE) for climbing or for approved crane lifts unless they are explicitly marked with WLL (Working Load Limit) and CE/EN certification.
