Kenter Shackle is the most widely used detachable connecting shackle for marine anchor chains. It is designed to connect individual 27.5 m (15-fathom) anchor chain shots into a complete anchor cable while allowing chain sections to be separated for inspection, maintenance, or replacement without cutting the chain.

The shackle is manufactured from forged alloy steel through closed-die forging, followed by machining, heat treatment, dimensional calibration, and mechanical testing. The assembly consists of two forged body halves, a center locking block, a taper locking pin, and a lead plug. After assembly, the locking system secures the shackle under repeated tensile loading while maintaining a profile similar to the adjoining chain links, allowing smooth passage through hawse pipes, chain lockers, and windlass gypsies.

Standard products are manufactured for U2 and U3 anchor chain systems with nominal chain diameters from 12.5 mm to 162 mm. Kenter Shackles are widely used on container ships, bulk carriers, tankers, LNG carriers, offshore platforms, FPSOs, floating production units, naval vessels, and permanent offshore mooring systems.

Package: Steel Pallet / Wooden Crate / Bulk Packing

Manufacturing Standards: Manufactured from forged alloy steel in accordance with IACS Unified Requirement W18, IACS Unified Requirement A1, ISO 1704, and the applicable requirements of ABS, BV, CCS, DNV, LR, NK, KR, RINA, and RS for anchor chain accessories. All load-bearing components are closed-die forged, heat treated, precision machined, and dimensionally calibrated to match the corresponding anchor chain grade.

Testing Standards: Each Kenter Shackle undergoes chemical composition verification, forging inspection, heat treatment verification, dimensional inspection, proof load testing, tensile property verification, hardness testing, magnetic particle inspection (MPI), visual inspection, assembly verification, and permanent identification marking before shipment. Material certificates, inspection reports, and classification society certificates are available upon request.

Application Standards: Suitable for connecting stud link anchor chains, studless anchor chains, offshore mooring chains, commercial ship anchor cables, container vessels, bulk carriers, oil tankers, LNG carriers, offshore platforms, FPSOs, floating production systems, naval vessels, and permanent mooring installations.

Maintenance Standards: Inspect the shackle regularly for body wear, deformation, center block wear, taper pin security, lead plug integrity, corrosion, cracks, excessive wear, and identification markings. Verify that all locking components remain securely installed after anchor handling operations. Damaged or worn Kenter Shackles shall be replaced immediately in accordance with the inspection requirements of the applicable classification society to ensure the integrity of the complete anchor chain system.
