Built for strength, durability, and reliability, Tidal Mooring Shackles are specifically designed to meet the rigorous demands of the marine and aquaculture industries. With a wide-mouth design, these shackles allow for the passage of heavy-duty hawser thimbles and large synthetic rope thimbles, eliminating the need for oversized, heavy shackles that can be difficult to handle.
Types of Mooring Shackles
Wide Mouth Mooring Shackle
Engineered primarily for the aquaculture industry, this high-tensile steel shackle provides a wider throat opening to accommodate heavy-duty hawser thimbles and large synthetic rope thimbles without having to size up to a larger shackle or increase weight of the shackle.
Tidal Mooring Shackles are manufactured with alloy steel and quenched tempered to provide our customers with safety and reliability they count on. Every shackle is manufactured and tested to meet ISO9001 standards ensuring the product to be void of hydrogen embrittlement.
