About this product
The Master Lock 640EURD is a 40mm marine padlock designed for use in highly corrosive coastal environments where persistent salt spray is an issue. It suits securing outboard motors, marine equipment, tackle boxes, trunks and larger storage containers where a medium level of security is needed. The padlock has a nickel-plated solid brass body with a stainless steel shackle, 6mm in diameter. It is key retaining, meaning the key can only be removed once the padlock is locked, and uses a 4-pin cylinder mechanism for reliable performance in demanding conditions. It comes with Master Lock's Lifetime Warranty against mechanical failure.
