The Mooring Snap Shackle is designed for easy and secure attachment to a mooring ball. Load floating mooring line or the metal ring into the snap shackle and close the gate and lock the pin. The Mantus Mooring Snap Shackle features a locking pin to ensure the gate stays locked once secured. It is made from Duplex Stainless Steel which is stronger and more corrosion resistant.
Currently available in 1/2 inch and 5/8 inch version

Mooring snap-shackle sizing
The gate closes around a mooring ring or pendant and a secondary locking pin helps keep it closed. The body is 2205 duplex stainless steel.
| Size | Recommended chain | Recommended anchor line | Breaking strength |
|---|---|---|---|
| 1/2 in (13 mm) | Up to 3/8 in (10 mm) | 1/2–3/4 in (12–20 mm) | 16,300 lb (7.4 t) |
| 5/8 in (16 mm) | Up to 1/2 in (13 mm) | 3/4–1 in (20–25 mm) | 22,000 lb (10 t) |
The mooring pendant or ring must fit freely inside the closed shackle and remain aligned with the load. Inspect the spring at least annually.
