Leadseals 100 Security Cable Seals Numbered Tags - Tamper Evident

Our review of the Leadseals 100 Security Cable Seals finds them best suited for logistics teams and small fleets that need an inexpensive, single-use tamper-evident solution. The biggest reason to buy is the clear, sequential serial numbering combined with a pull-tight, self-locking cable that makes tampering obvious while staying simple to apply. For anyone securing trailers, containers, utility boxes or delivery vans who values traceable seals and quick installation, these tags offer practicality and visible deterrence.

Key Features

• Sequential numbering: Each tag is printed with a unique progressive serial number for easy identification and chain-of-custody record keeping.
• Durable construction: ABS plastic housing with zinc casting and a steel wire core provides a balance of corrosion resistance and visibility in outdoor conditions.
• Adjustable locking length: The pull-tight, one-piece self-locking design lets users set the locking length to suit doors, latches or valves.
• Waterproof marking: The printed numbers are resistant to water and fading, keeping the ID readable during transit and storage.
• Practical size: A 300mm (11.8in) total length with 1.8mm (0.07in) wire fits most container, trailer and truck sealing points without extra tooling.

Who It's For

These cable seals are ideal for small to medium shippers, delivery services and maintenance teams that need an affordable tamper-evident seal they can apply quickly by hand. They work well for securing cargo doors, milk vehicles, oil tankers, utility boxes and rail or truck applications where visual tamper evidence and recordable serials matter.

Customers who need the highest physical protection against determined attacks should look at bolt seals or higher-security locking systems instead, since these single-use cable seals are designed primarily to indicate tampering rather than resist heavy cutting.

Pros & Cons

Pros

• Clear, sequential serial numbers make tracking and audits straightforward.
• Easy, one-handed pull-tight locking is fast for high-volume use.
• Waterproof printed markings and ABS housing hold up in wet conditions.
• Good value for routine tamper-evident sealing across trucks and containers.

Cons

• Not as physically strong as bolt seals, so not recommended where cutting resistance is required.
• A few users noted mixed impressions of strength versus price, so consider application risk before relying on them for high-value cargo.
