Pull-up cable seals: how to choose them and use them

Pull-up cable seals are a great option when wire or plastic seals are not strong enough or are unable to cope with the physical environment. They are perfect for preventing easy opening with malicious intention as they require specific tools.

How to pick the best pull-up cable seals for your needs

These adjustable seals come in a wide variety of types, sizes and lengths. The purpose will determine which are most suitable. If they are needed to fit into difficult spaces that alternative seals cannot manage, the longer, thinner options may be ideal. These can be bent or turned more easily.

If your main concern is use as a security seal that is as resistant as possible to being tampered with, consider the heavy-duty pull-up cable seals. These are very strong and can be a helpful barrier but are also stiffer and will need more space to be fitted.

An additional important consideration is the material the cable seal is made from. Aluminium seals are resistant to corrosion, which can make them ideal to more exposed environments. Aluminium is also one of the few truly recyclable materials, so it is good for environmentally conscious use, as discussed in this article from the BBC. Steel cable seals tend to be stronger, and any markings will be stamped directly into the seal, so they tend to be more durable. For more information about available options, click here.

What are pull-up cable seals used for?

This type of seal is commonly used on the valves for trucks, container doors, control panels, meter boxes and gates. They can be used as tags for high-value items, machinery, storage containers and vehicles.

It is always recommended that cable seals are used with proper record keeping and inspections.

To use a cable seal, it must be connected parallel to where it extends and attaches from. It must be firmly pushed to insert, and it is vital that the seal is pulled tightly. Loose seals are much less secure. After installing, always pull on any cable seal to test their tightness.

For removal, use shears (bypass) of good quality; if they are particularly heavy-duty cable seals, consider larger cutters. Pull-up cable seals should always be disposed of after use by hammering the body or removing markings.
