Steel Padlock with 2-Inch Shackle

This laminated steel padlock is built for lockout and safety procedures where a visible, colour-coded lock is required. The black finish and 2-inch extended shackle suit industrial panels, valve handles and gate hasps that need extra reach.

Fits Standard Lockout Points

The 5/16-inch shackle diameter and 5/8-inch horizontal clearance slide through common hasp holes and lockout devices without modification. A non-removable keyway keeps the key captive while the shackle is open, reducing lost-key incidents during shift changes.

Keyed-Different for Individual Control

Each lock opens only with its own key, so one worker cannot open another's lock during group lockout. The pry-resistant laminated body and steel shackle resist forced entry, though the 3/4-inch body thickness limits use where ultra-compact hardware is specified.

Questions about this item

How long will the 5/16 in steel shackle resist cutting under sustained attack?

The 5/16 in hardened steel shackle is rated pry resistant and designed to withstand prolonged cutting attempts, though exact time depends on the tools used.

Does the black laminated steel body heat up or become difficult to handle after staying locked outdoors all day?

The 1 1/4 in high steel body with black laminated coating absorbs some heat in direct sun but remains operable; gloves are recommended for extended handling in high temperatures.

What keying system must I already have for this padlock to integrate with my existing locks?

This unit is supplied keyed different with a standard key style; it does not share a key code with other locks unless a locksmith rekeys it to match your current system.
