Just got the lock a couple days ago. It was very easy to install on the coupling. Seems to fit perfect. Quality seems to be very good. Hopefully I'll never have to find out if it saves the trailer from being stolen.

First of all I want to say it is wonderful working with a company that actually cares about how their products are viewed by customers! Thank you. As for the lock itself, I am very happy with it. It is so easy to install and disconnect. I feel very confident in its ability to protect my trailer from theft.



by:

Fit perfectly on our new flatbed trailer. It stays in our hay stackyard away from the house, with the new lock we have no worries of it disappearing. Service from etrailer was fast and economical, thank you etrailers !!!!



by:

The lock for the gooseneck we bought will do the job we needed. It was shipped very timely which is very helpful.



by:

This is an impressive design. Took a bit of playing with it to figure out how it mates up with the gooseneck, but then, BINGO, fits perfectly.

A quality piece, and a very reasonable price, considering what you get.

And, Made in America! What’s not to like!



by:

Bring a hack saw if you think of stealing my gooseneck trailer with this lock on it.



by:

Does not fit Bulldog BX1 coupler, otherwise looks nice. etrailer did a great job helping me troubleshoot.

The fifth wheel lock will not fit a shocker hitch unless you do some grinding on it

Thanks for your business and your review, R T. I am sorry to hear about your lock. For ultimate protection, combine this coupler lock with Blaylocks EZ Lock for gooseneck coupler set screw BLTL-51-40D - sold separately, which secures your adjustable couplers inner tube to the outer tube.



by:

Company was great to work with. They did what they advertised and on time. They gave delivery updates. The Gooseneck Coupler Lock fit my trailer hitch. Ordering the padlock and hitch lock together is the way to go. The round style padlock is difficult for someone to attack or cut, due to its shape and design. Very satisfied overall.



by:

Works well on my goose neck horse trailer. No modifications needed. There is about a half inch of space between bottom of coupler and lock. I was expecting it to fit a little more snug. But seems like it will do the job. Great fast shipping. Will order from these guys again.



by:

First time I have delt with this company, very impressed. The have an excellent communication network, e-mails throughout the process.

The gooseneck trailer lock was exactly want I wanted. Sturdy, heavy grade aluminum lock that will deter even the most aggressive thief. Easily installed and removed by the owner. Will definately order another one one for my new flatbed trailer next month.



by:

Product fit my Logan trailer great. Only takes a few minutes.

Works great! Now let those MF’s try to steal my gooseneck trailer. HAHA

I feel so secure with my gooseneck locked. Still love your product.



by:

I recently purchased a Blaylock gooseneck lock as well as gooseneck setscrew locks and wheel chocks. I was so pleased with the gooseneck lock I purchased from etrailer in the past that I ordered a second one. Shipping was fast and accurate.



by:

Enjoyed the prompt service and quality product!



by:

The coupler lock fit my Superior coupler well and was easy to install and remove. Like any security device it could be defeated with some effort, but it will slow them down and require them to make some noise. The lock is made of materials that shouldn't rust or corrode so it outside storage is not a problem.



by:

  • Options For Lock on Square Tube Gooseneck Coupler
    We do have a couple of options for locks on a square tube gooseneck coupler, though I was unable to find the brand of coupler for Quality Trailers. So what you can do is just take a look and see what brand you have, if you don't happen to know off-hand. That will allow you to choose the right coupler lock from the two below: - Bulldog/Stallion/Superior/T.E.M.

  • Blalock EZ Lock that Could Fit B-B Gooseneck Trailer
    I don't have a way to determine what coupler your trailer has which is needed to determine what Blaylock gooseneck coupler lock fits but we have a few options. If you have a Bulldog, Stallion, Superior, T.E.M. you'd want the part # BLTL-50-40D, or if you have the RAM coupler you'd need the part # BLTL-55-40D. If you have something different let me know and I'll let you know what the best option would be.

  • Recommended Gooseneck Coupler Lock for Puma Trailer
    We have a few different options depending on the gooseneck coupler you have on your Puma trailer. If you have a Bulldog, Stallion, Superior, or T.E.M. coupler then I recommend the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50-40D. If you have a RAM coupler then you would need the # BLTL-55-40D instead. Both of these have an option to come with the Blaylock EZ Lock for Set Screw on Gooseneck Coupler - Aluminum # BLTL-51-40D.

  • Recommended Gooseneck Coupler Locks For 2012 Sundowner Rancher Trailer
    Many of the gooseneck locks we offer are designed to fit specific hitches and styles. If the gooseneck you have on your 2012 Sundowner 20 ft Rancher is a Bulldog, Stallion, Superior, or T.E.M. coupler, then I recommend part # BLTL-50-40D. This includes a stainless steel padlock. If your gooseneck is made by RAM, I recommend the Blaylock EZ Lock Gooseneck Coupler Lock, part # BLTL-55-40D. We do offer combo locks that secure both the coupler and the inner tube like part # BLTL-57-40D2...

    Thank you for the photo of your coupler. When choosing a lock for the coupler it makes it much easier if you are able to identify the coupler manufacturer.

  • Gooseneck Coupler Lock Compatibility
    Thank you for your photo of a gooseneck coupler lock which is similar to the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50. We do have gooseneck coupler locks for various brands of couplers. Locks # BLTL-50 and # BLTL-50-40D will fit on Bulldog, Stallion, Superior and T.E.M. gooseneck couplers. Lock # BLTL-55-40D fits Ram couplers only. With multiple trailers you will probably be best off using a multi-fit lock.

  • Gooseneck Coupler Lock For 2-5/16" Gooseneck
    There isn't a lock that uses a ball, but there is a surround lock for your gooseneck coupler, which is effectively the same, as it goes over where the ball inserts. For that use the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50-40D.

However, I looked up the Fulton GN24 Gooseneck Coupler Head and believe I have another option for you in the Blaylock EZ Lock Gooseneck Coupler Lock part # BLTL-50-40D which works with Bulldog Gooseneck Couplers like what the Fulton GN24 Gooseneck Coupler...

    The Blaylock EZ Lock Gooseneck Coupler Lock part # BLTL-50-40D that you referenced works with most adjustable gooseneck couplers therefore it should work with yours as well and after looking at your photos I don't see any apparent issues. That said, I was not able to identify the exact model you have based on either photo and the only way you will be able to do this is by reaching out to the trailer manufacturer. I have attached a dimensional photo that may help with determining compatibility...

  • Recommendation For A Gooseneck Trailer Lock
    The MasterLock High Security King Pin Lock, Item # ML387, is not compatible with your Big Tex Gooseneck Trailer. The MasterLock is for fifth wheel trailers and will not work with gooseneck trailers. We do have some gooseneck locks like the the Blaylock EZ Lock Gooseneck Coupler Lock, Item # BLTL-50-40D, that will work if you have a Bulldog, Stallion, Superior, or T.E.M. coupler. If this will not work for you, let me know which coupler you have and I will look for other options.

  • Trailer Lock Recommendation for a Trailer with a Bulldog Gooseneck Coupler
    I have a great theft-deterrent for your trailer that has the Bulldog Gooseneck Coupler part # BD0289340317 installed on it, but the Blaylock coupler lock part # BLTL-50-40D that you referenced would not be it. Instead you would need to go with a wheel lock like the part # RA-25 that works regardless of the coupler style of the trailer.

  • How Does Gooseneck Trailer Lock, # BLTL-50-40D, Attach to a Gooseneck Coupler
    Basically, the Gooseneck Trailer Lock, # BLTL-50-40D, sandwiches around the bottom of the gooseneck coupler on the trailer. The two hooks that look like duck heads go over the lip on one side and then you hold it up flat against the bottom of the coupler, and then you insert the pin that will be over the lip on the other side of the coupler.

  • Gooseneck Coupler Lock for 2015 PJ 32 Foot Gooseneck Trailer

As long as your trailer still has a Bulldog coupler, you will want to use Baylock EZ Lock Gooseneck Coupler Lock - Bulldog/Stallion/Superior/T.E.M. Gooseneck Couplers. For just the coupler lock without an included padlock, you will want to use part # BLTL-50. For the coupler lock with an included padlock, you will want to use # BLTL-50-40D.
