Tamper‑Evident Padlock Seals & Meter Seals

(When and Why to Use Them)

Tamper‑evident padlock seals (often called meter seals) are a practical choice when you need a fast, one‑piece seal that’s easy to apply and easy to inspect. They’re commonly used on utility meters and meter boxes, electrical panels, valve positions, equipment covers, storage cabinets, and other access points where you want clear evidence of interference without using a keyed padlock.

These seals are designed to show tampering if someone tries to pry, twist, or remove them, helping teams spot issues during routine site checks. For better accountability, many options can be supplied with unique serial numbers and custom marking (company name and numbering sequences), making it easier to track assets, document inspections, and support chain‑of‑custody records.

If you’re choosing between styles, consider the shackle/hasp opening size, the environment (indoor/outdoor), and whether you need sequential numbering or custom printing for internal controls.
