Frequently Asked Questions

AI
A security seal is typically a one-time-use item designed to show evidence of tampering, while a security bar is a permanent or semi-permanent physical barrier designed to stop an intruder from entering.
Common household applications include installing security bars over windows to prevent break-ins, or using swing bar guards on doors to allow ventilation while maintaining a security barrier.
Prioritize seals that meet ISO 17712 standards for high-security shipping, as these are more difficult to bypass and are recognized globally for cargo security.
