About this product
This 54mm padlock from the Master Lock ProSeries range is a compact, high-security option suited to gates, sheds, storage units, fences, containers and chains where space is limited but robust protection is still needed. It features a boron alloy shackle, 8mm in diameter and 19mm high, protected by a shrouded design for extra resistance against cutting and sawing. Inside, a layered laminated steel core and dual ball bearing locking mechanism combine to resist prying and forced entry, while a precision 6-pin cylinder offers strong pick resistance. A snap-on cap shields the cylinder from dirt and damage, and the xenoy outer casing gives good resilience against weather and corrosion. The key is retained in the lock body, and the padlock carries a lifetime warranty against mechanical failure.
