Master Lock Disc Padlock (Model M40XTCCSEN)

Engineered for professionals and homeowners alike, the Master Lock Disc Padlock delivers uncompromising security in a compact, weather-resistant design. Its stainless steel body and covered keyway shield the internal mechanism from moisture and debris, while a Tough-Cut™ octagonal boron-carbide shackle stands up to cutting and sawing attacks. The fully shrouded shackle exposes minimal material to bolt cutters, and dual ball-bearing locking provides maximum pry resistance.
