Tuff Stuff TUF3100LS door lock

Solid brass padlock with long shackle

The Tuff Stuff TUF3100LS is a 1-inch solid brass body padlock designed for outdoor durability and indoor convenience. Its corrosion-resistant construction suits gates, sheds and storage units exposed to weather. The compact size also fits hobbyist cases and lockers where space is limited. Buyers needing a high-security rating or a shrouded shackle for bolt-cutter resistance should look elsewhere.

Simple keyed installation

The padlock operates with a standard keyway; no tools, codes or batteries are required. Insert the key, turn, and the long shackle clears thick hasps or chain links. Misplacing the only key is the most common issue, so keep a spare in a safe place. There is no combination reset or electronic backup if the key is lost.

One-inch brass body for everyday security

The solid brass body resists rust and handles typical outdoor exposure without seizing. It comfortably secures garden gates, toolboxes and hobby storage. The shackle diameter and length are fixed, so it cannot accommodate oversized chains or high-security hasps that demand a thicker shackle. For heavy-duty industrial use, a larger hardened-steel model is more appropriate.
