A Lock Designed for Harsh, Salt-Water Environments!
3210 Double Sided Marine Grade Keyless Dead Bolt Lock Satin Chrome on Gatebox

If you are looking for a heavy duty keypad/combination lock that is specially designed for salt water environments, then take a look at this one.

This Marine Grade lock is Teflon-coated to resist salt water as well as blowing wind and sand. The patented Teflon finish protects it from corrosion due to exposure to salt from the ocean or even from road salt from trucks during winter if you are near a highway.

This lock will look like it just came out of the box for many years even under these harsh conditions. It even comes with a Life-Time Manufacturer's Warranty.
