4 pins/locks, 1 key...Outstanding! Very Pleased!
These seem to be a very good product this is what I needed to finish the job. Plus gives me the sense of security.
I put this hitch on my 2017 Winnebago Vista (Base 2017 Ford F-53), I needed to update the default hitch that was only 5000lbs to flat tow my truck which was just over weight at 5600lbs and yes I double checked the max the winnie can pull which is 7500lbs. So now I have more than I need to pull the weight. As some of you may know, looking for an affordable hitch for something that is custom is difficult. I did look into the universal weld-on but that would not work either as there is a bracket that was in the way to hold the generator. I was not looking to cut and weld. This bolt-on fits great and looks good. The receiver sits just under the original location by 2 inches.
Wished I'd had this item earlier. When I purchased my Blu Ox system the local RV dealership did not carry a similar item. So, etrailer is a life saver for useful products to the outdoor community. This package provides a number of keys, so you can have one on each family member's key ring -- truck, RV, and SUV. Love that one key can unlock/lock each hitch-pin on the Blue Ox flat tow system; no more fumbling with multiple keys. And, provides added security while away from your rig.
Well made!
Had an issue with what I received. It was quickly resolved and new items shipped out.
I’m a happy customer!

Works great! It’s nice to use one key to lock and unlock all four pins.
Exacrlly what I needed
Everything needed to set up our Jeep Wrangler for flat towing. A very straightforward installation, and great customer support!
Everything went in good, fit sung no pl ay
The product seems great, but it is the service I found incredible. One of the locks seemed to be bent iside and sometimes it stuck and sometimes it would not latch properly. I was not going to use a defective item to hold onto a new Jeep and called etrailer to see if it could be made right easily. At first they tried to see if they had one in stock that could be used as a replacement, but with the same key since all 4 are keyed the same. No luck, so etrailer called me back and they had contacted Blue Ox to have a replacement with a matching lock shipped directly to me. It showed up Fedex only a few days later. Not too often one finds service like this. Since they I have ordered more items. And will continue to do so.

Performing fine. The tow car has not detached once using these locks, Isnt that the best measure? Occasionally squirt a bit of lubricant in lick mechanism
All components very well made and solid, with good finish. Delivery packaging offered good protection. Installation instructions clear.
Service from etrailer.com was excellent - questions answered fully and promptly before order placed, price promise to match other supplier prices honored, order out for delivery within 24 hours with tracking information, and e-mail sent immediately after products delivered with supplier product info and instruction PDFs all gathered together in one place.

Thanks for the very professional follow-up on the Blue Ox products I bought. In the end, I only used the set-up for about 3,000 miles before I changed my rig from a Class C towing a Jeep Wrangler using the Blue Ox parts to a Jeep Grand Cherokee towing an Airstream. Everything worked just fine for those 3,000 miles and all the parts have been sold on, practically as new, on [on-line].
As always absolutely great buy, you are all amazing. Thanks Cindy
Good quality locks
Nice to get it all in one number.
this lockset is what I need to keep my tow bar secured to my tow vehicle and RV.
Works great. Fast shipping
Great product that provides assurance your toad stays attached! It takes a bit longer to attach due to the locking/unlocking however these pins will not accidently loose a cotter pin and come out. Well worth the small inconvenience.
As advertised. These locks fit perfectly. Be aware that the key must be in the lock and turned to install. The key stays in unlocked position, and must be turned to locked position to remove key. This is probably best way, since once the key is out you know it's installed correctly, since key won't turn unless all the way on or off.

Great. Having all keys the same really makes hook up easy.
Excellent service and quality produci yjamk you much
Solid lock pins - all keyed the same! Great product at a reasonable price. Shipping was very fast. Thanks etrailer!
This set is great for securing the tow bar to the base plate tabs as well as the tow bar and high-low adapter to the hitch all with one key. Convenient!
Can't pass along enough praise for you folks! Ordered these, along with a pair of safety cable extensions, on Easter weekend. Received an email notifying shipment... on Easter day! While not a large order, I needed them for a trip the following week, so was concerned they wouldn't arrive in time. Even though I didn't request rapid shipping, they arrived in plenty of time. Thanks much!
Quality locks- all keyed the same- ideal for flat tow setup- I also have a hitch adapter to drop my level- the 4th lock came in handy
