Protect your trailer with the Bulldog BT Brenderup Hitch Lock, a heavy-duty security device designed specifically for Brenderup trailers fitted with the Knott KFT100-1040 hitch head.
 
Manufactured from 4mm thick steel, the Bulldog BT uses an enclosing bottom-channel design to protect the hitch head and its fixings from tampering and unauthorised towing. Its compact construction makes it straightforward to fit and convenient to store, making it particularly useful for trailer owners who regularly travel with their trailer.
 
With Sold Secure approval, Secured by Design recognition and insurance approval, the Bulldog BT provides robust, British-made security for compatible Brenderup trailers.
 
Designed for Brenderup Trailers
The Bulldog BT is specifically designed for:
Brenderup trailers
Knott KFT100-1040 hitch heads
Compatible Brenderup trailer hitch configurations
 
Because the BT is designed around a specific Knott hitch head, always check that your Brenderup trailer is fitted with the KFT100-1040 before ordering.
 
Heavy-Duty 4mm Steel Construction
The Bulldog BT is manufactured from 4mm thick steel, providing a strong physical barrier around the trailer coupling.
 
Its bottom-channel design encloses the hitch head and its fixings, helping restrict access to important components and making forced removal more difficult.
 
High-Security Lock
A drill and pick-resistant high-security locking mechanism provides additional protection against common methods of attack.
Combined with the heavy-duty steel body, this creates a robust security solution while retaining a compact design that's practical for regular use.
 
Dummy Ring Protection
The Bulldog BT incorporates a dummy ring designed to restrict access to the towing point while the trailer is unhitched.
This helps prevent an unauthorised vehicle from connecting to the trailer and towing it away.
 
Compact and Easy to Use
The BT has been designed to provide substantial protection without being unnecessarily bulky.
 
It's quick and straightforward to fit, while its compact size makes it convenient to store with your other towing equipment when not in use.
