About this product
This Master Lock 640EURDLH is a 40mm marine padlock with an extra-long, 51mm stainless steel shackle (6mm diameter), designed for use in highly corrosive coastal environments where salt spray is a constant issue. The nickel-plated solid brass body resists corrosion, while the long shackle provides extended reach for securing thicker hasps, larger chain links or multiple fixing points. It uses a 4-pin cylinder mechanism and is key retaining, meaning the key cannot be removed unless the padlock is locked. Suggested uses include outboard motors, marine equipment, tackle boxes and trunks.
