Alock W

Polycarbonate seal with transparent capsule and coloured anchor. The anchor is pre-assembled with a standard 16cm length 0.81mm stainless steel wire. Other lengths of 25, 30, 39, 50, 79cm are available. The anchor is semi inserted into the capsule to protect against tampering of the locking pins before closure (fake sealing). The numbers are laser printed on both the tab and the anchor. The laser printing of a bar coded seal is on a white background on capsule with matching number on the anchor. Personalisation can be laser marked on capsule. The wire attached to the seal is of a thickness that enables it to pass through very small apertures and the choice of various sizes doesn’t limit its sealing length. A versatile seal for countless applications in the Air, Maritime and Road Industries, Commerce, Public Services and Armed Forces.

Although it looks very different, this Alock seal is based on the same concept as the series of Anchor Seals, which have been universally tested and approved since 1978. The Alock seal has two separate parts, a transparent capsule and a coloured anchor, both of which are of Polycarbonate plastic material. The transparent capsule facilitates the visualisation of the contrasting coloured anchor, and enables the inspection of the locking pins and reading of the numbers, which are printed on the anchor and are the same as those on the capsule. To make it a one-piece seal, and to prevent the locking pins from being tampered with before closure, the anchor it is pre-inserted into the capsule. The large tab on the capsule has sufficient space for Laser printed sequential numbers, or a bar code printed on a white background, as well as space for personalisation. The seal is supplied with a pre-assembled stainless steel two spiralled 0.81mm wire, in lengths of 16, 25, 30, 39, 50, or 79cm, or can be supplied without the pre-assembled wire.
