Body and terminals are AISI 316 acid-resistant stainless steel, with a bronze thread insert for smooth adjustment and long service life. The round body takes an adjustable spanner and carries a measurement slot to check terminal distance, and the polished rounded locknuts will not chafe sails or ropes.
