Wherever you go, Master Lock protects you. Protect your boat, camper, or ATV with a Master Lock trailer hitch lock.
Sealed and capped for peak performance in all weather.
Whether you’re moving, camping or towing, Master Lock has locks that provide security wherever you go.
Master Lock has a variety of locks designed to ensure your trailer is safe when you’re on the move or parked, including:
Hitch pin locks replace standard non-lockable hitch pins to help prevent someone from removing the hitch from your vehicle. A coupler lock prevents the trailer from being attached to a vehicle, so you can securely leave it at a campsite or jobsite.
No towing lock is a one-size-fits-all solution, so start by identifying your security needs. If you want to prevent someone from unhitching your trailer, choose a hitch pin or receiver lock and ensure that they’re the same size as the standard hitch pin you’re replacing. If you need to prevent someone from hitching your trailer to their vehicle, select a coupler lock instead. It’s also important to confirm the weight class of the towing lock, which should exceed your gross trailer weight and tongue weight.
Hitch pin locks and receiver locks are the best choices for tiny house owners because they prevent thieves from detaching and stealing the entire structure.
