hamma® Regatta Turnbuckle with Toggle is a marine-grade turnbuckle (rigging screw) for boats and yachts, available in 11 sizes.
Turnbuckles are used to set and adjust tension in standing rigging such as shrouds, forestays, backstays and lifelines. Sizes run from 1/4" pin to 1 1/4" pin; choose the size that matches your wire, pin or thread in the table below. Genuine Arcus hamma® hardware, supplied by ASW Marine Parts for boat owners across Australia.
Which size do I need? Match your wire diameter, pin or thread size to the size table. If you are replacing an existing fitting, measure the wire and pin, or quote the Arcus code. Dimension letters (A, B, L and so on) follow the Arcus catalogue drawing.
What load is it rated for? Arcus lists a minimum breaking load of 1,550 to 34,000 kg. Breaking load is not a safe working load; size your rigging with a suitable safety factor.
Do prices include GST? Yes. All prices are in Australian dollars and include GST.
