The Alko hitch head lock replacement provides strong security for Alko AK301 and AK351 hitches. Equally important, it fits many braked trailers, including boat trailers and most braked Brian James trailers. You can lock it whether the trailer is hitched or unhitched to your towing vehicle. Consequently, it stops anyone from raising the towing handle, preventing unauthorised coupling or uncoupling with a tow ball. For extra protection, pair the Alko head lock replacement with an SAS dummy towball when you unhitch the trailer. This combination completely stops coupling attempts using modified towballs. Also, it provides peace of mind when you leave your trailer unattended. This lock comes supplied with two security keys, ensuring reliable access control. Furthermore, the lock offers easy installation and smooth operation with your existing Alko hitch.
