What is a Master Lock® Shrouded Padlock?

Master Lock ProSeries® Shrouded Padlocks are High-Security padlocks. The Solid Iron Shroud provides more security than a standard padlock. A standard padlock’s shackle is visible and vulnerable to bolt cutters, sawing, and filing. Shrouded padlocks are protected from these common ways to tamper with a padlock. The shroud, which is an added cover to protect the shackle, deters unauthorized entry.

The Master Lock Company currently manufactures three Shrouded Padlocks: Master Lock Model No. 6321, Master Lock No. 6325, and Master Lock No. 6327. The Shrouded Padlocks are laminated steel padlocks encased in an exclusive cover. This cover is resistant to ice, water, and dirt. The main difference between these padlock models is their body widths. The 6321 is the leanest, at a 2-1/8in. body width. The 6325 is in the middle, with a body width of 2-3/8in. Lastly, the 6327 is the widest, with a 2-5/8in. padlock body.
