Product Overview
NS2587 Type A bulwark mounted chock is a welded mooring fitting designed for guiding mooring lines through the ship’s bulwark.
Manufactured in accordance with NS 2587-1982 Norwegian Standard, it provides smooth rope lead and reduces wear on synthetic and wire ropes.
The fabricated steel plate structure ensures reliable strength and is widely used on European vessels for deck edge mooring arrangements.
Designed for bulwark installation where space is limited and controlled rope guidance is required.
