The padlock is highly resistant to corrosion, offering excellent protection from the elements. The dual compound body cover provides comfortable handling. It can be coded and re-coded as required and they can be coded alike, so one code opens several locks. The combination wheels are spaced comfortably apart, making them easier to use with push button operation. The recodable mechanism offers 10,000 possible combinations on the 4-wheel.
