The TOPONE Kenter Shackle is a detachable joining link for connecting compatible anchor chain sections. Its forged alloy steel body, center chock and locking pin form a secure connection while allowing chain sections to be separated for inspection or replacement. Available configurations are selected to match the chain grade, diameter and anchoring system.
The Kenter Shackle is one of the most widely used detachable connectors for marine anchor chains. It joins individual 27.5 m (15-fathom) anchor chain shots into a complete anchor cable. Its detachable construction also allows 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. Its assembly consists of two forged body halves, a center locking block, a taper locking pin and a lead plug.
Once assembled, the locking components secure the connection under repeated tensile loading. The shackle maintains a profile similar to the adjoining chain links, allowing it to pass through compatible hawse pipes, chain lockers and windlass gypsies.
· Chain grades: U2 and U3
· Nominal chain diameters: 12.5 mm to 162 mm
· Primary function: Joining anchor chain shots while allowing sections to be detached for maintenance
· Applications: Container ships, bulk carriers, tankers, LNG carriers, offshore platforms, FPSOs, floating production units, naval vessels and permanent offshore mooring systems
The Kenter Shackle must be matched to the chain grade, nominal diameter, adjoining links and anchor handling equipment specified for the complete system.
Selection requires more than matching the nominal diameter. Confirm the chain grade, stud link or studless configuration, mating link geometry, windlass compatibility and applicable project or classification requirements. For a complete system, explore TOPONE’s Stud Link Anchor Chain, Studless Link Anchor Chain and End Shackle.
TOPONE’s factory covers more than 15,000 m², including over 5,000 m² of manufacturing warehouse space. With experience in anchor chain production, our team can review the Kenter Shackle alongside the corresponding chain sections and related accessories. We check the required grade, dimensions, assembly configuration, testing requirements and traceability documents when preparing a matched supply proposal. www.toponechain.com

Name: Kenter Shackle
MOQ: 100 Pieces
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.
