ARK Trailer Coupling Lock ATL15 – Chrome Heavy-Duty Towball Lock with Dual Lock System (SKU: ATL15)

ARK Trailer Coupling Lock – Chrome Anti-Theft Towball Lock with Dual Lock System (SKU: ATL15)

The ARK ATL15 is a heavy-duty, chrome-finished trailer coupling lock designed to deliver solid anti-theft protection whether your trailer is hitched or unhitched. Built tough with a durable dual-locking system, it secures the coupling from both directions—making it significantly harder to tamper with or bypass.

Finished in corrosion-resistant chrome plating, this lock not only performs under harsh Australian conditions but looks the part too. The ATL15 suits a wide range of trailer couplings, including popular models from ALKO, ARK, Cruisemaster, and Hitch-Ezy, making it an excellent universal choice for serious trailer owners.
