Additional Information
- Concealed shackle padlocks significantly reduce cutting attacks but do not protect against prying if the hasp or staple is weak or poorly aligned.
- This model is commonly used by locksmiths on roller doors where exposed long shackles are repeatedly cut.
- Because clearance is limited, installers should confirm staple alignment before selecting a concealed shackle padlock.
- Brass bodies offer corrosion resistance but are softer than steel and rely on the concealed shackle design for attack resistance.
