Locking Hitch Pin
Hitch Locking Pin fits all 2″, 2.5″, and 3″ receivers. The usable length of the pin portion is 3-1/2″ long (Regular) or 4-1/2″ long (Long), with a diameter of 5/8″.
Also known as a locking hitch pin or trailer hitch lock pin, this stainless steel pin secures your ball mount or hitch to your vehicle’s receiver, protecting it from theft when your trailer is unattended. It features a 2-key lock cylinder for stronger security than a standard pin-and-clip setup, and locks or unlocks with a quarter-turn of the key. An included rubber dust cap keeps the lock cylinder protected from rust and debris.
If you already own a Weigh Safe hitch or lock, this pin can be keyed alike to your existing key; you just enter your key code at checkout, or select “000” if this is your first Weigh Safe lock.
The regular pin should fit most receivers; however, if you have a truck with a 3″ receiver with a thicker material, the long hitch pin will be a better fit for you. Heavy-duty or oversized receivers, such as those used in Class V hitches or commercial towing setups, may have thicker walls that increase the total width the hitch pin needs to span. In those cases, you should use the long hitch pin (WS05-L).
FAQs
How does a locking hitch pin work?
A locking hitch pin replaces your receiver's standard pin and clip with a keyed lock. The Weigh Safe Hitch Locking Pin slides through your receiver and coupler like a normal hitch pin, but instead of a simple clip, an internal mechanism locks in place and only releases with the matching key. That means your trailer, cargo carrier, or hitch-mounted accessory can't be disconnected by anyone who doesn't have the key, while you can still remove it in seconds when you do.
Are locking hitch pins worth it?
Yes. A locking hitch pin is one of the cheapest ways to deter theft of whatever's on your hitch, since a would-be thief can't pull the pin without the matching key. At $31.50 to $35, it costs a fraction of what you'd lose to a stolen trailer, cargo box, or bike rack, and it only takes a few extra seconds to lock or unlock compared to a standard pin. It's especially worth it if you leave a loaded trailer or accessory unattended, tow regularly, or park overnight somewhere you can't keep an eye on it.
How to lock a trailer hitch pin?
Line up your trailer coupler or accessory with the hitch receiver, then slide the locking pin through the aligned holes. Insert the key and turn it to engage the internal lock, which secures the pin so it can't be pulled back out. Remove the key and store it somewhere separate from the vehicle. Before installing, confirm you've got the right length for your setup: the Weigh Safe pin comes in Regular (3.5" usable length) for standard receivers and Long (4.5" usable length) for receivers with thicker walls, so it fully seats and locks correctly.
What is the best lockable hitch pin?
The right lockable hitch pin comes down to matching it to your receiver size and wall thickness. The Weigh Safe Hitch Locking Pin fits standard 2", 2.5", and 3" receivers and is available in two lengths: Regular for standard receivers, and Long (4.5" usable length) for heavy-duty or oversized setups like Class V hitches and commercial towing rigs. Getting the length right matters just as much as the lock itself, since a pin that doesn't match your receiver's wall thickness won't seat and lock properly.
