Perfect for the Demco EzLatch on my utility trailer. Very easy to use and provides the security for my trailer that I sought.

Works very well, and as intended. Adds a sense of real security & safety.

Good value since the coupler lock works exactly as intended. Best part - even tho outside year around in Seattle weather, no corrosion since chrome plating more than adequate. Works on both electric and surge brake couplers with thru-body locks requiring extra length (span).

I was sent a follow up email asking how I liked the lock, and I have to say that I liked it enough to buy it a second time after I LOST THE KEYS!!! Because losing keys in my job!!! But yes it is a great lock for my trailer, because it has an odd coupler that a pin goes completely through it and you can’t use a standard padlock or coupler lock. The coupler locks sold at local stores were not long enough to go through the coupler, so I has to search the internet and I found this at trailer.com and it works! I would definitely recommend this lock if you have this style of coupler.



- e98888
by:

I bought this coupler lock, because my hitch was too wide for a standard coupler to work. It works fine and looks great. It is a pain to have to keep turning the key around and around to "unlock" the device from the hitch. From a theft or security perspective, it is awesome.

Exactly what I needed to lock my 2 trailers. Keyed alike locks for ease of use. 1 key that’s all. Thanks

Great product! I bought this coupler lock to replace others that kept bending while pulling my boat. After a year and fishing about once a week, pulling over mountains, and having to hit the brakes hard a couple of times, this coupler has held up superbly! etrailer is my go to place for all trailer products, great selection of products, super description of their products, often with video link, fantastic service and very competitive prices!

I am so happy that I received my Surge Brake Coupler Lock. I can now sleep soundly knowing my personal belongings will be safe while I travel from Houston, Texas to Washington State. Thank you Steve for your help in finding the product I need!



- e98888

I like the product - wasn't sure I liked the way you have to screw the key on the lock on to the pin assembly. Not a traditional key lock. However, after a few times of use works well.



- e98888
by:

Seems to be good quality. It is a 'screw on' type of lock, not a click and release but I suppose this is a bit safer and less likely to come apart mistakenly.



- e98888
by:

Works as advertised and feel safe knowing my trailer is secure. I have it on a boat trailer and came back to the launch this winter and another fisherman had his trailer stolen. No lock on his and they just took the easiest one.

Just installed on trailer. Looks to be well made. Fit like a glove and keys worked well. We will see how well it holds up, my guess I think it will be fine.

Very nice lock for a specific trailer tongue you have. The lock is well built. Just hoping it’ll be bullet proof when it comes to thieves. Other than that I’m happy with the product.

  • Coupler Pin Locks that Can be Keyed Alike
    We have coupler pin lock locks that can be keyed alike like the part # e98888 which has a span of 3-3/8 inches and # e98887 which has a 2-1/2 inch span. Or even # e98890 with a 7/8 inch span or # e98886 which has a 2 inch span. On the product page you'll select keyed alike on the drop down menu and all of the locks will use same key.

  • Difference Between Keyed Alike and Keyed Unique on DeadBolt Coupler Lock
    When looking at our etrailer.com Coupler Lock # e98888, or any of our etrailer.com locks, "Keyed Unique" means that each of the locks you purchase (if you purchase more than one) will use a different key. If you select "Keyed Alike" instead, each of the locks you purchase (again if purchasing more than one) will use the same key, making it much easier to keep track of if you have multiple trailers. If you are just purchasing one unit then it does not matter which option you choose (although...

  • Recommended Hitch Pin Lock For UFP A-60 Coupler
    The coupler lock I recommend for your UFP A-60 Coupler is the Coupler Lock, part # e98888. Since the coupler measures 3-inches wide and the pin hole is 1/4 inch diameter the # 28012 will work great to secure the coupler. The lock has a covered key slot to keep dirt and helps prevent corrosion. This is a keyed-alike item so if you want more than one lock and need them all to use the same key you can use the drop-down box on the product page when ordering.

  • Compatibility of etrailer Coupler Lock on a 2-5/16 Inch Bulldog Coupler
    Good news, I can help you figure out if this coupler lock will fit your Bulldog coupler. As long as your pin diameter on the Bulldog coupler is larger than a 1/4 inch and the span is no bigger than 3-3/8 inches, then this coupler lock will work for you. I pulled the Bulldog coupler # BD028287 you had looked at from our warehouse and a similar style 2-5/16 inch # BD028499 and measured the size of the lock pin that goes in the coupler. It measured 5/16 inch diameter and a length of...

  • Recommended Coupler Lock For Trailer With A 3" Span
    We have exactly what you are looking for. I recommend the etrailer Surge Brake Coupler Lock # e98888 which has a 3-3/8" span which will work perfectly to lock your coupler when it is attached to a hitch ball, or even when it is not. The # e98888 has a chrome finish making it corrosion resistant, and the tamper proof design will keep your trailer secure. I included a video of the # e98888 for you to take a look at.

  • Coupler Lock Recommendation for a Demco Coupler
    I really wish we had a coupler lock in the dimensions you listed, but the closest thing we offer is the part # e98888 that you referenced that has a 1/4 inch diameter pin that is 3-3/8 inches long. The difference would only be 1/16 of an inch so this lock should still work for you. There's no reason it wouldn't. Another option you have is a coupler lock like the part # DT25013KA. This lock can fit nearly any coupler and should work well for you.

  • Recommended Equipment Needed to Lock Boat Trailer to 2013 Ranger Trail
    If you already have a hitch receiver lock then you can use a coupler lock, like our etrailer.com part # e98888 that you referenced, to deter theft of your trailer. However, if you do not already have a hitch receiver lock then I recommend using something like the Bulldog Lifelong Trigger-Style Coupler Lock and 2" Trailer Hitch Receiver Lock # BD580404 instead. This will help to deter someone from simply removing your ball mount to steal your boat trailer. The receiver lock is compatible...

If there are two identical boat trailers parked side by side, one using the # e98888 lock, and the other unlocked, the lock will do its job and deter the crook from taking your trailer. One quick snip with some bolt cutters, and the lock will be defeated, but the...
