High Security Bar Lock Seals - 10 Per Box
For trailers, tankers, and containers with multi-point or heavy-duty latch systems, high security bar seals deliver the strongest barrier protection in our catalog. Each bar lock seal pairs a solid metal locking bar with a reinforced shackle housing, engineered to resist cutting, prying, and drilling, and to show unmistakable evidence if anyone tries.
This box of 10 high security bar seals, priced in USD and shipped from domestic stock. Each seal is individually serialized, so every unit in the box carries a unique, traceable number for chain-of-custody documentation.

Applications
Bar lock seals are built for the highest-risk cargo movements: full container loads on international ocean freight, cross-border trailers carrying high-value goods, tanker and hopper car multi-point latches, and any shipment where your compliance program calls for the strongest available barrier seal rather than a standard bolt or cable option.
How to Install
-
Align the locking bar with the shackle housing on your container, trailer, or tanker latch.
-
Insert the bar fully into the housing until it locks, the mechanism is one-way and cannot be reopened by hand.
-
Record the serial number on your shipping documentation before dispatch.
-
Removal at destination requires bolt cutters or a hydraulic shear tool; any seal that isn't intact on arrival should be treated as a potential tampering event and documented immediately.
Frequently Asked Questions
What are high security bar seals used for?
High security bar seals are barrier-class tamper-evident seals used on containers, trailers, tankers, and railcars with multi-point or heavy-duty latch systems, where maximum resistance to cutting and prying is required.
Are these bar seals C-TPAT and ISO 17712 approved?
Yes. Every bar lock seal in this box of 10 is manufactured and lab-tested to meet ISO 17712:2013 "H" (High Security) classification and C-TPAT approval requirements for international cargo shipments.
How many bar seals come in one box?
This listing includes 10 high security bar seals per box, each individually serialized for tracking and compliance documentation.
How is a bar seal different from a bolt seal?
A bar seal uses a solid metal locking bar and shackle housing, offering greater resistance to cutting and prying than a standard bolt seal, making it a common choice for higher-risk cargo or multi-point closures. A bolt seal remains the standard for single-point container and trailer latches.
How do I remove a bar lock seal?
Bar lock seals must be cut using bolt cutters or a hydraulic shear tool (sold separately); they cannot be opened by hand, which is what makes them tamper-evident.
