Heavy-Duty Trailer Security
The Bulldog TC400 Trailclamp provides a strong physical and highly visible deterrent when your trailer is parked, stored or left unattended.
 
Its main arm is manufactured from rolled-edge steel, while the integrated protection disc restricts access to the wheel nuts and helps prevent unauthorised wheel removal.

The TC400 features a straightforward two-part construction with no complicated pre-assembly required.
 
Simply position the clamp around the compatible wheel and secure it using Bulldog’s plunge locking system. It can also be locked without using the key, making it quick and convenient for regular use.
 
High-Security 10-Pin Lock
The TC400 features a 10-pin drill and pick-resistant locking mechanism offering over one million possible key combinations, providing additional protection against attempted attack.
