About this product
This Master Lock marine padlock has a 50mm wide stainless steel body, designed for maximum strength and corrosion resistance in wet or coastal conditions. It suits securing marine equipment, outboard motors, tackle boxes and trunks. The shrouded stainless steel shackle offers strong cut resistance and added protection against bolt cutter attacks. A 5-pin cylinder guards against picking, while dual deadbolt locking resists prying and hammering, giving reliable security in demanding outdoor and marine environments.
