Steel Padlock for Safety Lockout

This Master Lock padlock uses a laminated steel body with a red finish for clear identification in lockout procedures. The 5/16 inch diameter steel shackle extends 2 inches to fit through larger hasps or multiple isolation points. A standard keyed-different cylinder ensures each lock in a set opens only with its own key, supporting individual accountability on site.

Pry-Resistant Body and Extended Shackle

The 1 1/4 inch tall body is 3/4 inch thick and coated in red laminate that resists corrosion and tampering. Horizontal and vertical shackle clearances of 5/8 inch and 2 inches respectively allow the lock to engage bulky energy-isolation hardware without binding. Non-removable key design keeps the key captive while the shackle is open, reducing the chance of accidental unlocking.

2 Inch Shackle Height for Wide Clearance

The 2 inch shackle height is the critical dimension that determines whether this padlock reaches through oversized lockout hasps, chain links or valve handles. Buyers who need a shorter shackle for tight clearances or a taller shackle for very large hardware should verify the required reach before ordering.

Questions about this item

How do I install the padlock and what step is often missed?

Insert the 5/16 in steel shackle through the hasp, close the lock body, and verify the non-removable key cannot be withdrawn while the shackle is open — that final check is the step people skip.

What maintenance or replacement will this padlock need later?

Lubricate the cylinder and shackle pivot with a dry PTFE spray once a year; replace the lock if the 5/16 in shackle shows deformation, the laminated steel body cracks, or the keyed-different cylinder binds.

What limit appears first under sustained outdoor use?

The red bumper and laminated coating resist weather, but prolonged exposure will degrade the finish before the 5/16 in steel shackle or pry-resistant body loses structural strength.
