The Cargo Mate Towbar Lockable Hitch Pin is straight-up towing gear that locks your towball and coupling to square receiver hitches with 5/8 inch or 16 mm pin holes so you can tow the van or box trailer without the tongue wandering off. The L-shape gives clearance around standard Hayman Reese style bars and still pulls tight through the hitch, which keeps the coupling planted on rough back roads and corrugated access tracks.

This kit runs a solid metal pin sized to fit 16 mm receiver holes and a matching lock body with a knurled metal grip, so you can work it with cold or dirty hands at the campsite. The lock cap and two keys handle normal day-to-day security when you duck into town, and the whole setup is built tough for regular towing from the suburbs to the highway and out to the campsite.

Q: Does this hitch pin work with all Hayman Reese style towbars?

It suits Hayman Reese and similar square hitches that use a 5/8 inch or 16 mm pin hole. Always check your receiver uses this pin diameter before you buy. Measure the existing hitch pin on your vehicle or refer to the towbar plate. If the hole size is different this gear will not seat correctly.

Q: How is the lock on the pin operated?

The lock is built into the end of the L-type pin and is operated with the supplied keys. You insert the key into the lock body and turn to release or secure the end section. The pin then slides through the receiver and coupling before you refit the lock. This layout keeps the load on the solid shaft while the lock holds the assembly in place.

Q: Is this hitch pin suitable for use with caravans and heavy trailers?

It is intended for use with caravans and trailers that use a square receiver hitch with a 5/8 inch or 16 mm pin hole. The pin secures the towball mount to the vehicle while the towbar and coupling carry the rated load. Always match the trailer weight to the towbar and vehicle ratings as listed by the manufacturer. The hitch pin should never be used to exceed those limits.

Q: Can I leave the lockable hitch pin on the vehicle when not towing?

You can leave it installed in the receiver if you want the towball mount to stay on the vehicle. Some drivers remove the tongue and pin when not towing to improve rear clearance. If you leave it fitted check the lock and pin for dirt and corrosion as part of your regular towing gear inspection. Keep the key somewhere secure but accessible when you need to remove the hitch.

Suits Hayman Reese and other square style slide hitches that use a 5/8 inch or 16 mm hitch pin hole. Fits standard square receiver towbar setups that match these pin dimensions. Always check the pin hole diameter on your existing hitch receiver before installation. Install the L-type pin through the receiver and coupling then lock the end cap with the supplied keys.
