Choosing a seal is really a three-part measurement job: cable diameter, cable length and locking-point geometry. This guide places the published specifications side by side so you can see what is confirmed, what still has to be requested, and which configuration fits the door, cabinet or gate in front of you. The CA-1.5A aluminum cable seal anchors the comparison — a steel locking mechanism inside an aluminum casing, a 300 mm cable and unique serial numbering — and the same tamper-evident construction runs through the wider range offered as a high security cable seal for freight, utility and high-value supply chain applications.
How the seal behaves
A cable seal is not hardware you fit and forget — it is a control you record at dispatch and verify at receipt. The product is described as a tamper-evident, single-use seal, which means the value sits in the evidence it leaves behind rather than in the strength of the fitting alone.
Published specification
These are the values carried on the official product page. Where a field exists but no figure is published, it is shown that way rather than filled in with an estimate — a gap you can close with a datasheet request is better than a number nobody can stand behind.
| Specification | Published detail |
|---|---|
| Material | Steel locking mechanism with aluminum casing |
| Cable length | 300 mm |
| Diameter of steel cable | 1.5 mm |
| Packaging | 1000 pieces per box |
| Marking | Unique serial numbering for traceability and audit compliance |
| Body treatment | Corrosion-resistant coating on the aluminum body |
| Dimensions | Not published — request the datasheet |
| Breaking strength | No numeric figure published — request the test report |
The product page states that breaking strengths exceed industry benchmarks for high-strength cable seals, but it does not print a number. If your specification, customs file or insurer requires a figure, ask for the test report before you commit to a bulk order.
Scenario to specification
Work through these three measurements in order. Each one narrows the configuration, and each one ends with the decision that moves you either to a standard part or to a custom request.
Find the hasp, bar, bolt hole or gate loop the cable has to pass through and measure its opening. The standard CA-1.5A uses a 1.5 mm steel cable, while wire diameter options are described as customizable to application requirements.
1.5 mm standard → confirm a larger diameter with the factoryAdd up the distance from where the seal body will sit to the point where the cable closes. The published cable length is 300 mm; the manufacturer also describes flexible cable length configurations for different locking points.
300 mm standard → request a custom length for long runsThis seal is designed to be applied once and cut off. The locking technology irreversibly signals an intrusion attempt, so a seal that has been opened cannot be closed and reused. If your process needs a reusable fastener, a cable seal is the wrong control.
Single-use → order in bulk against the spec above
Casing decision
Aluminum is the sensible casing when the locking point is a loop rather than a latch, and when the seal itself has to carry readable information for months of outdoor service.
Marking and records
Unique serial numbering is the one feature on this product that changes how you operate, not just how you buy. It is listed for traceability and audit compliance, which only pays off if the number is written down somewhere at each handoff.
Additional marking such as a company logo, barcode or a defined serial range is not published on the product page. If your process needs it, raise it with the factory as part of a bulk order enquiry rather than assuming it is included.
Application map
Each application below pairs a real product fact with the decision that actually slows a first order down.
Trailers, cargo doors and container gates are the load-bearing use cases named for this product. The serial number gives every handoff a single recorded reference instead of a verbal description.
Decide first: who writes the serial down at dispatch, and who checks it at receipt.
The corrosion-resistant coating on the aluminum body is what makes outdoor cabinets a realistic fit. The 300 mm cable has to reach from the cabinet housing to the valve or box loop without stretching.
Decide first: whether the standard 300 mm run clears the cabinet edge, or a custom length is needed.
Inspection rounds are routine and repetitive, which makes the twist-and-lock procedure — no specialised tools — the deciding feature here.
Decide first: annual seal consumption, so 1000-piece boxes are ordered before the inspection cycle, not during it.
The irreversible tamper-evident signal is the core control for bag and container transfers, where an interrupted seal has to be obvious rather than arguable.
Decide first: the serial range and reconciliation sheet used at each collection point.
Locking components engineered against cutting and forced entry suit movements where an external party may inspect the documentation.
Decide first: whether a customs or insurer file needs a breaking-strength test report before release.

no numeric breaking strength is published on the product page. the copy states that breaking strengths exceed industry benchmarks for high-strength cable seals, but no figure is given. ask for the test report if your specification or insurer requires a number.
start with the aperture of the hasp, bar, bolt hole or gate loop, then measure the run from the seal body to the locking point. the standard ca-1.5a uses a 1.5 mm cable and a 300 mm length, and both wire diameter options and cable length configurations are described as customizable to application requirements.
no. it is a single-use, tamper-evident seal. the locking technology irreversibly signals an intrusion attempt, so a seal that has been removed cannot be re-fitted and reused.
installation is a twist-and-lock procedure that the manufacturer states requires no specialised tools. seals are packed 1000 pieces per box, and each seal carries unique serial numbering for traceability and audit compliance.
