Stainless & Bronze

With its elegant and functional design, this turnbuckle is the natural choice for both new builds and rigging upgrades.

The body and terminals are made of acid-resistant stainless steel AISI 316, ensuring maximum durability in marine environments. A bronze thread insert reduces friction, providing smooth adjustment and long service life.

The round body features a distinctive wrench grip for a firm hold with an adjustable spanner.

Locking is handled with polished, rounded locknuts – a stylish and user-friendly solution that also protects sails and ropes from chafe.

A slot on one side allows for easy measurement of the distance between terminals studs. 

Hint - when you are satisfied with your tuning, make a note of these distances to simplify next stepping of your mast.
