Video Transcript for Review of Weigh Safe Hitch Locks - Standard Pin Lock - WS05

Jeff: Hello, everybody. This is Jeff at trailer.com. Today we're going to take a look at this Weigh Safe 5/8" Diameter Stainless Steel Hitch Receiver Lock for 2", 2-1/2", and 3" Hitch Receivers.Now, you'd use this in place of your standard pin and clip on your hitch receiver. This lock would prevent somebody from taking your ball mount or your hitch accessory like a bike rack or cargo carrier. It is a nice stainless steel pin and lock construction. Does use a high strength ball interlock design to lock it.

And if you notice on the end here it has this nice cover to key slot with the rubber cap to prevent any rust and corrosion. You just put that over the lock, prevents any dirt from getting into the lock cylinder. It is a tube key lock cylinder, which will provide a lot better security than your standard key lock cylinder. The tube key cylinder will make it harder to pick, more difficult to duplicate keys.Does come with two keys with this, and again, it's a very easy to use design. Just requires a quarter of a turn of the key to unlock it and remove it, and to install it, just slide it right back on.

Turn it a quarter of a turn. Remove the key, put your cover on, it's locked into place.Application, this again is for 2" by 2", 2-1/2" by 2-1/2", and 3" by 3" hitch receiver. The pin diameter is 5/8". Overall length from one end to the other, if we put a ruler on that, you can see is going to be right at 6". The inner span or the inside span or what they call the usable length, which is the measurement in here, this is going to be right at about 3-1/2".

And what I'm going to do now is, let me zoom out just a little bit, I'm going to pull up a 2" by 2" hitch receiver. It has a ball mount in it, you can see right here, and it's using your standard pin and clip.So what you want to do is anybody could come along and just pull off your clip, pull out your pin, and then remove whatever you have in your hitch, either the ball mount or your hitch accessory. What you want to do with this is like we mentioned, take the cap off, put your key in there, turn it a quarter of a turn, unlock it, slide this through, all the way in. Put it on there, turn it a quarter of a turn to lock it. Then you can see it's locked in place.

Put your cover on there to protect it, and then nobody can just pull your ball mount or your accessory out. It's locked there unless you have the keys to remove it. And to remove it again, just put your . quarter of a turn removes it, and just like that, very simple installation.But that should do it for the review on the Weigh Safe 5/8" Diameter Stainless Steel Hitch Receiver Lock for the 2", 2-1/2", and 3" Hitch Receivers.

Looks great and fits perfectly well on my 2014 F250. 520129

- WS05

Amazing customer service and shipping was fast. They also followed up with us to make sure we got our shipment and that we were happy with the product.... That is a thing of the past that I miss and etrailer seems to still hold up those values.. Highly recommended!!! 434639

Appears to be well constructed and I like the round key as opposed to a conventional key as they tend to resist corrosion in the working parts better than their conventional bretheren. I use it on a 2 1/2" reciever and it fits satisfactorily. 637186

Lock looks great and very substantial, should hold anything I have to pull. Thanks for the speedy shipment. 505394

Absolutely great, would order another one if I ever need one.

This is a good quality pin but it is a little difficult to turn the key to lock the end on without pushing the pin partially out. I don't fully trust that it's locked so wind up pulling on the end. It has always been locked but I'm a little leery of the way it locks on, just some balls that move into and out of a detent. Pretty pricey for what it is. Since I will rarely leave my hitch on, I'll probably just use a conventional pin most of the time. Wish my Weigh Safe hitch and pin were keyed alike also. Not sure how that could have been ordered but would do that in a do over. 617171

Still feel the same about this pin. I use a regular pin with a clip unless I need to leave the hitch installed. Would be nice if the manufacturer saw fit to put a hole in this pin so that you could use a spring clip plus the locking end.

Great product and fast shipping definitely 5 star service! 634585

Not easy to find a pin for a 3” receiver. My 2017 Ford F-250 Super Duty has a 3” hitch mount. This pin works great with my B&W Tow and Stow three ball hitch. For the money I spent on that hitch I needed to be able to lock it to the truck. This pin is perfect. I did have to grease the pin to get it to fit into the holes but it did eventually go once I got them lined up. 463446

After a year the lock pin has performed as expected. I would highly recommend if you have a high dollar 3” hitch that you want to keep attached to your truck.

Doesn’t seem to be many hitch locks out there for a 3” hitch, this one works very nicely. Would’ve been nice to have the option to have keyed alike (since I bought everything together) without buying all the extra parts I don’t need but we are a wasteful world these days. 455382

The dust cover on the lock quickly dry toys and crumbles after leaving your hands black, the keys are flimsy had to order replacements very quickly, I quit using this after about 6 months. Can’t take stars away it looks like.

Ordered the Weigh Safe WS10-25 drop ball mount with the Weigh Safe receiver lock. The hitch looked like it was used. The Weigh Safe sticker had been removed and the unit was gouged on the shaft and ball mount. This may have been a return item that was shipped to me. I'm very disappointed. I expect a new product, not a used or poor quality second. First time buying from etrailer. Most likely my last. 419071

I had some trouble sliding this pin in through my hitch. Had to tap it in with a hammer. Seems well made just a little tight. 750265

- WS05

Lock is well made and as advertised 938809

- WS05

Works very well, no complaints. The rubber keyhole cover does a great job deflecting road grime. Used it throughout last winter with zero issues freezing up or getting full of dirt/salt. 935355

- WS05

Only reason it isn’t five star is it wasn’t keyed the same as the hitch! It would have been perfect had it been. 934947

- WS05

Solid item. Just like the picture. 934788

- WS05

I love it 928563

Very well made lock. Round socket key is much better than traditional flat. 900292

- WS05

Lock failed and I had to have it cut off. Etrailer provided great customer service, but the manufacturer was a bit difficult to work with. They did replace it, but I am skeptical about using the replacement. 897707

Did not rust closed while being used for a year, like similar locking pins.. 896507

- WS05

Have not used yet, check back in 3 months of use. 894897

- WS05

Corroded such that key was unusable such that I have not been able to remove. Looking like I might need to purchase a new blade for sawzall and cut it off. 894663

Love the product ! 894092

Nice hitch, easy to adjust and easy to read the tongue weight. Locking feature is nice so it can’t be removed from your truck. 882839

Just keep it greased and it works great one year later. 867465

Extra theft protection worth the extra money. 866664
