Bulldog DM Alko / Albe Hitch Lock heavy-duty hitch lock suitable for Alko and Albe hitch heads up to 92 mm wide. Crafted from 4 mm thick steel, it completely encloses the hitch head and fixings when fitted, providing reliable protection against theft — whether your trailer or caravan is hitched, unhitched, or secured with a Bulldog lock post.
Engineered for convenience, the DM is quick to fit, compact to store, and equipped with a high-security drill- and pick-resistant lock. The dummy ring restricts access to the towing point for added defence, while the design’s proven strength has made it a consistent best-seller among UK trailer and caravan owners.
Praised in leading magazines such as Practical Caravan, Auto Express and Caravan Club Magazine, the Bulldog DM is a recognised market leader in hitch security. Approved by Sold Secure Gold, Secured by Design (UK Police), and Insurance Approved, this lock delivers the highest level of confidence and protection.
