Before you can begin the process of using a cable seal, you need to select the appropriate one. This will depend on the application and security requirements. Typically, there are two types of cable seals: wire and metal.
The cable is attached to the object you want to protect, such as a container or truck. To do this, the cable is threaded through the locking mechanism, which then seals the cable.
You need to tighten the cable seal to ensure it is secure and can prevent any attempts to tamper with the object. This is done by pulling the cable through the locking mechanism and tightening it.
Every cable seal has a unique number or barcode that is used to track it. It is important to record this number to ensure proper security and traceability.
After installation, you should inspect the cable seal to ensure it has been properly installed and is intact. If the seal is damaged or has been tampered with, it must be reported and replaced.
When it is time to open the container or remove the cable seal, it is important to cut it off properly. This will ensure that the cable and seal do not cause any damages.
Steel
Cable seals made of steel are strong and durable, and are the most commonly used cable seals for securing cargo containers.
Aluminum
Cable seals made of aluminum are lightweight and corrosion-resistant, making them suitable for outdoor use.
Plastic
Cable seals made of plastic are inexpensive and easy to use, but are generally less secure than other materials.
Nylon
Cable seals made of nylon are strong and heat-resistant, and are often used in high-temperature applications.
Brass
Cable seals made of brass are highly tamper-evident, making them suitable for high-security applications.
Stainless steel
Cable seals made of stainless steel are highly durable and resistant to corrosion, making them suitable for outdoor use in harsh environments.
A steel cable is the central component of cable seals that ties together the locking mechanism, body, and the locking insert.
The locking mechanism is the part of the cable seal that secures the cable in place, preventing tampering and unauthorized access. It can be made of various materials, from plastic to metal, and can come in different designs, such as single-lock or multi-lock.
This is the actual locking element that connects with the cable's head to safeguard the seal in place. The seal employs a locking insert that grips the cable tightly when the locking mechanism is engaged.
It is where the locking mechanism and the cable are placed. The body of cable seals often has a structure that varies in shape and size based on the seal's specifications.
Cable seals usually feature anti-tampering measures such as visible markings, a higher breaking strength, or markings that vanish when the seal is broken, all of which provide added security measures for ensuring that the seal is not broken or tampered with.
The cable will have a varying diameter depending on the cable seal's requirements. Different diameters may be chosen to offer the desired strength, weight, and resiliency of the seal.
Lubrication
Apply a thin layer of lubricant to the cable seal to help prevent corrosion and prolong its lifespan. Use a high-quality silicone-based lubricant to ensure the best results.
Check for damage
Inspect the cable seal regularly for signs of damage or wear. If you notice any cracks, splits or other damage, you should replace the seal as soon as possible.
Regular cleaning
You should make sure to clean the cable seals regularly, preferably every six months or so. Use a soft cloth to remove any dirt or debris that may have accumulated around the seal. If necessary, use a mild detergent to clean the seal.
Keep the seal dry
Moisture is the enemy of cable seals, so you should do your best to keep the seal dry. If you notice any signs of moisture or water penetration, you should take steps to address the issue promptly.
Avoid excessive tension
Do not over-tighten the cable seal, as this can cause damage to the seal and the cable. Use only as much tension as necessary to create a secure seal.
Store the cable seal properly
When not in use, store the cable seal in a cool, dry place, away from direct sunlight and humidity. Avoid storing the seal in an area where it may be exposed to chemicals or other corrosive materials.
