How It Compares With The Alternatives
Compared with Pear shaped end shackle
Both are end fittings, the D type has the classic straight-sided body while the pear shape tapers to suit different end link geometry
Compared with D type joining shackle (lugged)
The end shackle terminates a chain run at the swivel, the joining shackle connects two lengths of chain together
How To Use And Maintain It
- Match the shackle grade to the grade of chain in the mooring line
- Specify the classification society before production starts
- Choose hot dip galvanized or black painting according to immersion exposure
- Check nominal diameter against the chain it connects
What We Need From You To Quote
- Size or diameter, and the grade if it is specified
- Quantity and packing format
- Surface finish for the environment it works in
- Classification society, if a certificate is required
- Destination port for freight
