Hitch-Ball Couplers
For an easy towing hookup, bolt or weld these couplers to a trailer. They connect to the hitch ball on a vehicle and secure with a lever latch. Maximum trailer weight is the total weight being towed.
Straight couplers bolt to a single-channel trailer tongue.
Height-adjusting couplers raise and lower to match the height of your hitch ball and level your trailer. This distributes the load on your tires better than straight or A-frame couplers. A spring-loaded latch on these couplers automatically opens and closes around the ball.
A-frame couplers weld onto a two-channel trailer tongue set at a 50° angle.
Couplers with a lockable lever help prevent accidental uncoupling while driving. They have a hole in the latch, so you can secure it with a pin, padlock, or coupler lock (sold separately). Some couplers include a pin.

Hitch-Ball Coupler Locks
Insert these locks into the hitch-ball coupler latch or socket on your trailer to prevent theft. Each lock is plated or powder-coated to stand up to weather, so you can use them on outdoor trailers without worrying about corrosion.
Style A locks block the latch lever, so no one can open the latch and connect their own vehicle without the key. These locks are a good choice when your vehicle and trailer are unsupervised, such as at refueling stops.
Style B and C locks block access to the socket, so no one can hitch your trailer without the key. These locks are a good choice when your trailer is unhitched from your vehicle, such as during drop-offs or while in storage. Style B locks are one piece and compact for easy installation and storage. Made of aluminum, they resist corrosion better than steel locks. Style C locks can also be used on ring-type hitches. Made of two hardened steel pieces, they’re heavy duty and stand up to attempts to cut them open better than aluminum locks.
Choose keyed alike locks if you need several locks that open with the same key. Choose keyed differently locks if you need locks that each open with a different key.
