Overview
Cable Security Seals
High Security Sealing Cables
Cable seals are very durable and intended for higher security applications. They are available in different cable diameters for use in different applications.
Typical Applications
Shipping containers
Trucks
Rail Freight
Utility meters and valves
Valves in petrochemical industry
To qualify as a 'high security' seal and comply with ISO 17712, the cable seal diameter must be a minimum of 3.5mm; this is the minimum cable diameter required to pass the shear test of ISO 17712.
All of our cable seals are manufactured in facilities which are C-TPAT compliant.
Our PREMIUM cable seals include these added features and benefits:
improved locking mechanism to combat tampering.
bar codes (128) that match the unique serial number for improved productivity.
a light-weight (but durable) construction to minimize shipping costs.
Cable seals are also configured as
adjustable length or fixed length.
Adjustable Cable Seals

After threading into the locking channel, adjustable length seals can be tightened for a snug fit.
Fixed Length Cable Seals

Fixed length seals are secured by inserting the metal pin into the locking chamber. Wrap the cable as needed to minimize slack before locking.
After the locking mechanism is engaged, the cable seal can only be removed with a cable or bolt cutter.
The cable is constructed of galvanized steel aircraft cable, which will unravel upon cutting. This feature minimizes unauthorized reuse of the seal, which might be attempted by re-threading the cut cable into the locking mechanism of an adjustable cable seal.
Cable seals are a one-time use product.
Choosing A Cable Seal....
All seals are suitable for indoor or outdoor applications.
All seals have unique serial numbers. Record the serial number for added security.
Some seals have bar codes for added convenience in recording the serial number.
Bar codes improve productivity and accuracy for larger projects.
If threading the cable through a hole, allow at least 10% clearance for cable thickness variation. For example, for a 1.5 mm cable, the hole size must be a minimum of 1.65mm diameter. Inadequate clearance may cause the cable ends to unravel, which will then interfere with inserting the cable into the locking mechanism.
Shorter cables cost less. Use the shortest length possible to reduce cost.
The 'usable' cable length for locking is typically 2 inches shorter than the actual cable length because the cable is tapered.
Medium length cables (36 inch) are ideal for securing only the 'keeper bars' on truck trailers while using another type of seal (or lock) secures the handle latch.
Long length cables (48 and 54 inch) are ideal for securing both the 'keeper bars' and the handle latch on truck trailers or shipping containers.
Thicker cables cost more. Use the thinest cable possible to reduce cost.
Shipments which cross international borders usually require a seal which is rated as High
Security.
For applications which require a high security seal that must comply with ISO 17712, the cable diameter must be a minimum of 3.5mm. We offer 3.5mm and 5.0mm cable seals.
Thicker cables offer more security because they require special cutting tools to remove them.
For applications requiring the best barrier cable seal,
use the 5mm cables.
Some cable seals have a plastic locking mechanism, which is better suited for non-conductive (thermal and electrical) applications.
Custom imprinted seals offer more security. Different background colors are available for color coding.
In addition to our extensive selection of stock cable seals, we can provide custom cable seals. Please call for more information.
Installing Adjustable Cable Seals
- Thread the loose cable end into the locking channel and push through the locking mechanism.
- Pull the cable snug to minimize slack.
- IMPORTANT: Pull on the locking mechanism (or reverse pull the threaded cable) to fully engage the lock onto the cable.
Installing Fixed Length Cable Seals
- Wrap the cable around keeper bars; minimize slack
- Push pin into the locking mechanism
- Pull on the cable to confirm the locking mechanism is engaged.
Removing Cable Seals
- Cut with bolt cutter or wire cutter; wear safety glasses.
For Improved Security....
- As an added precaution against unauthorized re-use, cut the adjustable cable at the fixed end -- not the adjustable end -- when removing.

To prevent re-use, cut the fixed cable end when removing
For fixed length seals the pin and locking mechanism are permanently sealed to the cable ends. Therefore, the fixed cable can be cut at any point.
- For added security, an optional custom imprinted hologram label can be added to the cable seal housing. Please call for more information.
