Setting the bar for cargo transit security
The LXR is a high-security cable seal integrated with the Red Flag STM (Security Transit Management) system.
Tamper-resistant
Independently tested by Dayton T. Brown for evidence of tampering: ratcheting, picking, sleeving, cable changing, and freezing.
High-security “H” seal
ISO 17712:2013 and C-TPAT compliant high-security “H” seal for international transit.
STM-integrated
Works with the Red Flag STM (Security Transit Management) system, so every seal is tracked from application to removal.
Mobile ready
Scan, filter, apply, and receive notifications on iOS and Android or the desktop application.
On real railcars, in real conditions
Installation photos from customer shipments.
Railcar installation
The 400 mm cable loops through the locking hardware; the stamped, QR-coded barrel logs straight into STM.
Sealed locking hardware
5 mm non-preformed cable resists ratcheting and picking, in any weather and any light.
Custom-branded barrels
Customer logo and serial number stamped on every barrel; the QR code scans straight into STM.
Locked to the latch
A second pass through the door hardware leaves no working slack for ratcheting or picking.
Trailer lock rods
The 1500 mm cable covers containers and OTR trailer rods; 400 mm for railcars.
Sealed door keeper
Independently tested for evidence of tampering — ratcheting, picking, sleeving, and freezing.
Built for railcars, containers, and OTR trucks
Every LXR ships individually bar-coded, ready to scan into STM.
