The compact BURG-WÄCHTER padlock set Duo 460 Ni 40 SB made of solid brass can be exposed to sea air for a long time without losing functionality. The surrounding plastic material of the 460 Yacht protects sensitive surfaces from scratches. The sturdy shackle is made of stainless steel, providing optimal rust protection. Additionally, the shackle is double locked. The compact brass construction also reliably protects the internal mechanism of the 460 Yacht from moisture and thus from corrosion.
