Flint Hill Goods Trailer Coupler Lock - 7/8" Span - Black Steel

The first one did not work well, but trailer quickly made it right by shipping me a replacement that works jusT fine.1721670

The large diameter of the body on this lock makes it interfere with the body of the coupler, so you cannot use it on a standard 2 15/16 travel trailer coupler latch as I had intended. I think I may be able to do a bit of grinding on the body to create some flats that will allow it to work because it is close to being able to work on my coupler.1387873

Product worked exactly as stated. The product was easy to code to my truck key. I am very happy with the Bolt trailer hitch lock, also was looking for a lock for my trailer coupler that was sturdy, easy and quick to unlock and the MaxxTow Trailer Coupler lock is Pretty much what I was looking for.828792

Lives in my trailer, so far so good. No significant wear/rust. Trailers lives outside, under a roof.1468713

Great service, thanks Josh. Fast delivery and excellent item.2002588

I’m very happy with this coupler lock. I’m using it on a Maxey utility trailer with a Demco Easy latch adjustable coupler. It was a little long for my application, so I used a rubber grommet to protect the finish on the coupler. Great product!818131

The only thing keeping it from being marked excellent is it is advertised as 3 5/8" span, it is actually only 3 1/2". If your application dictates 3 5/8" need, you will have to grind or turn some material from the inside under the head of the stem. Otherwise, it is well built and works as it should.1296219

Work well - process to lock them is kind of a pain though. Push on one end and hold cylinder from rotating to lock.1636435

Perfect for what I needed for the surge Brakes on my car EZ-Tow Dolly. I had previously ordered one that was 2-1/2" which should of fit but the hitch had some metal flares on it that made it necessary to get the longer one. Very good product - and I really like the round-cylinder key system. I recommend this product for anyone that has a surge brake system with the 1/4" shaft - pin locking system.864245

I use this to lock a bike carrier to a class I hitch (the 5/8" lockable pin won't fit through the bike carrier mount). Works awesome. The rubber cap stays secure.1435987

I bought this product and was pleased that the service and shipping was fast, but one of the locks fell apart the 1st time I unlocked it. The small lock that locks the trailer to my truck hitch just fell apart. The lock that locks the stinger to my reciever hitch was difficult to put on. My factory mounted trailer light plug below my bumper was to close to the stinger. I had to bend the key over at a 90 degree to get it to work, but I got several keys so its ok there. all in all I wouldnt buy this again or recommend this to a friend73268

Great product. Been using this coupler latch lock about a year now. It has kept my Airstream travel trailer locked and secured to the hitch ball while towing to 20 different States. I would purchase this lock again.1188795

These are heavy locks. They are spring loaded so it is just a turn of the key and they open. To close push in and turn key.1439152

Fit perfectly and quality is excellent. 864370

Very nice product. But, there is one exception -- the span is not 3-5/8" but actually 3-3/8". Probably just a type in the description. Other than that it will work just fine for my trailer coupler. Thanks!!1437389

I have a 2018 Ranger Trail boat trailer, and wanted a good lock to secure the trailer to my truck when I am off fishing. I went with the 3-5/8" to ensure that it fit well......... propably could have gone with the 3-1/2" and been fine. Looks good, I like the fact that it is a different type of key, which I hope is harder to pick, overall I am very happy with the purchase.917023

I bought a coupler lock for when my boat/trailer are detached from my tow vehicle and I bought a pin dog bone lock for the coupler when boat/trailer are attached to tow vehicle like when parked at the lake boat in water.1105709

We have a flat trailer and a boat trailer that we wanted to be able to secure to our vehicle. With the unusual size we looked at number of places but like other "special" items we found them at etrailer.com. They shipped timely and are of a good quality.947037

I have bought quite a few items from etrailer and I have not been disappointed.
This particular coupler latch lock is built better and I especially like the round key.1285942

I like that you don’t need the key to engage this lock. Mechanism feels smooth.1422647
