3.5mm Flexsecure Cable Seal (FS35) with ISO 17712:2013 Classification

The FlexSecure FS 35 is a 3.5mm cable seal, has a High-Security classification for the ISO 17712:2013 testing standards, and is C-TPAT and PIP compliant. This versatile security seal fits many applications and is popular for sealing bulk rail cars and intermodal containers and trailers. The non-preform cable frays wildly when cut and is galvanized for corrosion protection making the FS35 a popular choice of security seal in the Oil and Gas Industry. The patent pending locking mechanism inside the anodized aluminum housing makes sure your goods are safe in transit.

Flexsecure 35 Applications / Industries

Flexsecure 3.5mm Cable Seals are the ideal barrier seal for transportation and logistics security applications. The FS35 is also suitable for securing shipping containers, rail trucks, plastic distribution boxes, and petrochemical valves. It is also suitable for Cross Border Shipments between the UK and the EU for Brexit trades.

Flexsecure Sealing Procedure

The Flexsecure is easy to apply, just pull the cable through and tighten to minimise the loop for an extremely strong and secure tamper-evident seal.

We can supply sequentially numbered security seals from UK stocks in a range of standard colours, diameters, and lengths, as well as customised seals. For custom options please contact our customer services team.

Flexsecure Custom Marking Options

The FS35 seals can be supplied with laser marking of the company name/logo, barcoding, and custom sequential numbering.
