Product Description
24–48 Inch Cast Steel Kevel Chocks | ASTM A27 Mooring Rope Guide for Ship Deck
Product Overview
Cast steel kevel chocks are deck-mounted mooring fittings used to guide and secure mooring lines.
Manufactured from ASTM A27-70-36 cast steel, the structure is verified by finite element strength analysis and load testing.
The design minimizes rope bending stress and extends service life of synthetic mooring lines.
Surface is smoothly ground to protect ropes and ensure safe operation.
