About Features

The pin and bush is moulded with a high-impact ABS material. The special high-resilient ABS material does not break easily but will clearly show evidence of tampering.

Identical sequential numbers etched with laser technology on both barrel and bolt to prevent replacement of parts.

Standard markings include serial number, customer name/ logo. A variation of bar codes can also be marked with laser technology.

Available with a transparent plastic cover that protects the marking on the barrel.


Our innovative bolt security seals (pat. pending) design is characterised by two metal tabs attached to the bolt seal, which slot securely into the clo


sure canal of the “female” part of the security seal.

This amendment to the traditional bolt seal for containers design, requested by the new ISO norms, means it is no longer possible to  tamper the “female” part of the security seal by spinning it at high speed.

Any Tampering attempt will damage the seal leaving it irreparable.
