How to Select and Use Pull-Up Cable Seals

Posted by Steve Diebold

Choosing the right seal is a critical decision when security is paramount. Pull-up or adjustable cable seals emerge as the go-to option when conventional plastic or wire seals fall short in terms of strength, particularly in environments prone to extreme temperatures or physical impact.

The robust nature of adjustable cable seals serves as a deterrent against malicious tampering, requiring more substantial and less common tools to cut open compared to their wire and plastic counterparts. The versatility of adjustable cable seals not only addresses vulnerabilities associated with easy cutting but also adds an extra layer of protection, making them a formidable choice in environments where security is not just a preference but a necessity.

As we delve into the features and applications of these seals, it becomes evident that their strength and resilience play a pivotal role in fortifying security measures against unauthorized access and tampering incidents.

How To Select The Perfect Cable Seal For Your Needs

Choosing the appropriate cable seal for your needs demands a tailored approach to match your unique requirements. To streamline this process, check out our comprehensive 'Cable Seals' section on the website, where our team of security seal experts stands ready to assist you in identifying the ideal size, length, and type of cable seal for your specific application.

Diverse environments call for different cable seal characteristics. Longer seals with slender cables offer flexibility, enabling easy bending and turning to fit into spaces that may challenge other seal types. On the other hand, heavy duty cable seals provide a robust defense against cutting and tampering, although they require sufficient space for bending and locking due to their strength and stiffness.

Cable seals find popularity in various applications, from securing tank truck valves and container doors to tagging machinery, vehicles, and high-value assets. They serve as a secure alternative to locks in closures that aren't frequently accessed, making them an optimal choice when monitoring access via keys is not a priority.

Material selection plays a crucial role in determining a cable seal's performance. aluminum body seals, known for their corrosion resistance, offer the added advantage of laser markings, including logos and barcodes. Meanwhile, steel seals, with a sturdier body, feature durable markings physically stamped into the seal, typically limited to simple logos or alphanumeric characters.

Cable seals come in an array of lengths, ranging from 6 inches to 72 inches, and cable diameters spanning 1.5mm to 4mm. For those safeguarding international shipments, opting for a seal compliant with ISO standards is paramount.

AC&M proudly offers a selection of cable seals adhering to recognized ISO-17712 and C-TPAT standards for high-security (H) seals. As a leading cable seal manufacturer, AC&M maintains compliance with ISO standards and procedures globally recognized for high-security seals, holding the status of a registered seal manufacturer under ISO-9001:2008.

Optimal Usage And Handling Of Security Seals

Ensuring the effectiveness of security seals involves adhering to proper handling, meticulous record-keeping, and regular inspections. For instance, even the mere act of inserting a cable seal requires a methodical approach. The cable should be inserted parallel to itself into the corresponding hole, ensuring it aligns with the side where it is already attached and extends from the lock body. A firm push initiates the process, setting the foundation for a secure seal.

For pull-up cable seals, achieving maximum tension without causing damage to the attached device is paramount. A tight seal minimizes vulnerability to manipulation, emphasizing the need to pull and test the seal after installation, confirming it is securely tightened in place.

Post-cutting considerations are crucial, especially with seals whose cables fray or spread upon cutting, rendering them non-reusable. It is advisable to trim excess cable after sealing to prevent any potential reuse and reinforce security measures. When removing cable seals, utilizing a high-quality bypass shear is essential. Our product range includes the Model C7 cable cutter, suitable for light to medium cables. For heavy duty seals, larger cutters from electrical or industrial tool supply vendors can streamline the process.

Be sure to remember to responsibly dispose of used seals, which is integral to the security protocol. Complete disposal involves crushing the seal body with a hammer or destroying markings using a sharp tool. This ensures the integrity of the security system and prevents any potential misuse of discarded seals.
