Does Master Lock Trailer Coupler Lock # ML389DAT Come with a Cover for the Key Hole


Does this lock come with some type of cover to prevent sand and dirt from getting into the key hole ?


Expert Reply:

The Master Lock Trailer Coupler Lock # ML389DAT does not come with a cover for the key hole. The covers are a bit of a double edged sword though. On one hand they keep out dirt and debris, but on the other they trap moisture in the lock core which can cause corrosion to build.
