Total Control Over Trailer Access
Empower your operation with unmatched security. Take complete control over who is authorized to pull your trailer, where, and when. With the Admiral Hub, you can define access permissions in real-time, ensuring that only pre-approved drivers can engage and move your semi-trailer.
Enhanced Security Against Theft
Trailers are valuable assets and a prime target for theft. Our immobilization system ensures that your trailer can only be operated by authorized personnel, significantly reducing the risk of theft.
Prevention Against Unauthorized Use
Unauthorized use of trailers not only poses a risk of theft but can also lead to liability issues and operational disruptions. Our technology ensures that trailers cannot be used to steal trailers or for any unauthorized purposes.

Experience peace of mind with a security solution that integrates seamlessly into your existing operations. Drivers connect to trailers just as they always have. The Admiral Hub actively manages access, allowing only pre-authorized drivers to release the parking brake. This simple yet effective mechanism helps prevent theft and operational mistakes. The Valve, a robust and reliable component, acts as a passive on/off switch within the spring brake line, enhancing security without complicating the process.
Designed by industry insiders. Developed with insights from fellow owners and operators, our immobilization technology reflects practical, field-tested solutions that intuitively align with your needs, making you think, "Yes, that's exactly what I needed!"
Flexibility meets functionality. Keep your yard operations running smoothly with our optional universal trailer fob. This tool allows drivers to maintain their preferred workflows, automatically interacting with the Hub to secure the trailer when the right tractor connects and ensuring it remains secure when disconnected. No fob? No worries. The same secure, seamless functionality is available through a mobile app, providing keyless entry that’s as simple as unlocking your smartphone.

Set Parameters
Operators input specific access parameters via the Admiral Console, deciding who can access the trailer and under what conditions.
Smart Hub Activation
The Admiral Hub, installed on the trailer, enforces these parameters by controlling the Valve, which acts on the trailer’s brakes.
Secure Access
Only when an authorized driver’s fob or mobile app communicates with the Hub will the trailer’s brakes be released, allowing movement within designated safe zones and times.
Complete Oversight
Continuous monitoring ensures that trailers remain secure and operations comply with your standards, all easily managed through our user-friendly dashboard.
Parking Brake Only
The Immobilizer acts on the parking brake. It does not operate or interrupt the service brakes.
Commanded by the Hub
A pneumatic enforcement device installed in the trailer or tractor parking-brake line. It receives its commands from the Admiral Hub.
Safety Interlocks
Built-in safety controls prevent immobilization while the equipment is moving, or when other required safety conditions are not met.
The Hub, Lock and Immobilizer work together on the trailer as one system for sensing, authorization and physical enforcement. Set the conditions once and the trailer manages its own access and movement from there.
