RS PRO Key Aluminium Padlock, 6mm Shackle, 43mm Body

The mechanism and shackle are coated in an aluminium layer to keep them resistant to corrosion, so the lock won't rust up over time, even when in contact with chemicals. The colour cover makes the lock easily noticeable, alerting people of the restricted access. The mechanism is coated in a strong plastic to conceal it and provide an extra layer of protection from would-be lock-breakers.
