This rugged, rustproof aluminum trailer coupler lock simply yet effectively deters towaway theft of your gooseneck trailer that has a Bulldog, Stallion, Superior, or T.E.M. coupler. A second lock secures the inner tube. Includes 2 padlocks.


Features:

  • Set of 2 coupler locks deters theft of your gooseneck trailer that has an adjustable Bulldog, Stallion, Superior, or T.E.M. coupler
  • Coupler latch lock fits around base of trailer coupler to prevent access to latch
    • Narrow end slides over the coupler bracket near the handle
  • Set screw lock prevents removal of inner tube from outer tube
    • Secures around the set screw on the tube
  • Steel pins slide through the brackets to secure the locks to coupler's base and set screw
  • Stainless steel padlocks with hardened steel shackles secure pins in place
  • Aircraft-grade, lightweight aluminum construction is strong and resists wear and corrosion
  • 4 Keys are included
  • Made in the USA


Specs:

  • Application: most adjustable Bulldog, Stallion, Superior, and T.E.M. gooseneck couplers
  • Coupler latch lock dimensions: 11" long x 6-1/4" wide x 4-1/2" tall
  • Set screw lock dimensions: 3-1/8" long x 2-11/16" wide x 2-5/16" tall
  • Pin diameter: 3/4"


After it has been secured, this set of Blaylock EZ Locks renders the latch and the inner tube of your trailer's adjustable Bulldog, Stallion, Superior, or T.E.M. gooseneck coupler inoperable, ensuring your peace of mind. The base lock secures the coupler's latch. And the set screw lock prevents the removal of the inner tube from the outer tube, providing complete security. Simply position the latch lock around the base of your coupler, with the narrow end of the lock fitted over the coupler bracket near the handle. Position the other lock around the set screw. Then insert the 3/4" diameter steel pins through the holes in the locks and secure the pins in place with the included Master Lock padlocks.

This trailer locking system gives me the confidence I need to park my trailer outside with confidence and not have to worry about it disappearing.


Comments
Myyour trailer lock is great. Easy and convenient to use
Lawrence - 06/12/2022


by:

Works ok, little loose on my PJ Trailer gooseneck. Looking at the reviews again I see that I am not the only one to have this issue. However, I don't see anything which will work better, so I will just make a sleeve to go on the pin and tighten up the fit.


Comments
As long as the PJ trailers still outfit their trailers with a Bulldog gooseneck coupler then this lock would be a fit. The lock is 11 inches long, 6.25 inches wide and 4.5 inches tall.
-- Etrailer Expert Jenny N - 03/14/2022


by:

Something I should have purchased years ago. Fitment was easy. I had to get a bigger washer for the top lock, as my bolt was larger than the washer provide, but no big deal.


Comments
This product has worked great and continues to keep my trailer and contents safe. Again, wish I had purchased years ago
Allan R - 03/02/2020



by:

This hitch lock is excellent would definitely recommend to anyone. It has been out in the weather for a year now and there are zero signs of corrosion/rust on any of the components. The only thing that has room for improvement is the way it fits the bottom side, it fits a little loose but it's still impossible to remove without destroying it. Adds peace of mind letting your trailer sit somewhere knowing it's not going anywhere without a battle.


Comments
I have sold the trailer and the lock went with it but it was still holding up great when I last saw it!
Brad F - 09/12/2017



by:

I bought this as a birthday gift for my son. Was just what he wanted and has worked well for his trailer.




by:

Great concept easy to lock-up. It took me a little bit to figure the Gooseneck Coupler, my order did not have instructions.


Comments
Great good product.

so far, so good! No problems of any sort and my trailer has remained secure since.

by:

I’ve had one of these for 15+ years on another trailer and it still looks like new. The aluminum and stainless steel construction is very long lasting.




by:

Fit is excellent for horse trailer. Fits loosely on a PJ Flatbed Gooseneck




by:

Awesome products and arrived on time




by:

Product as described & arrived on time. I ordered this lock for my 3 horse gooseneck trailer. Website is easy to navigate, & excellent customer service when I called to order extra locks & keys. Super easy, would purchase again!




by:

This lock set is exactly as advertised. Fit our coupler perfectly. The quality is excellent. I recommend spending the extra for this combo set. We are more than satisfied with our purchase and the staff at etrailer.com are top notch.




by:

Quality lock. Worked great. Another good purchase from etrailer.com.




by:

Very good deal, even includes the padlocks - easy to use locks - great shipping


Comments
A great peace of mind when trailer is unattended.
Pam W - 04/22/2015



by:

I just got this product installed today. It seems well designed. Instillation was easy with the help of YOUTUBE. It looks solid but yet light weight. Hopefully it will prevent thieves from stealing my trailer. There has been issues in my neighborhood where there has been items stolen from people’s property. I hope it works.


Comments
I love this product. It is easy to use. I have two of them and one key works for both. I highly recommend this product.
John F - 01/30/2019



by:

Everything on the web site was exactly what I received and it fit nicely




by:

We bought three sets of these for our trailers. The product is very well made. We only received half of the locks in our first box, probably because most people don't order multiple sets. I called etrailer, and they quickly corrected the problem and shipped the additional locks. Very good customer service!




by:

I’m surprised I haven’t seen more of these being used on parked trailers. Previously I’ve seen many different styles of hitch locks and this one out classes the others by far. With its aluminum design and the hardened steel bolt in combination with the security lock it is premium in my opinion. With the cost of trailers in the current market this lock is cheap insurance.




by:

product appears well made and strong, it fit well out of the box, packaging was adequate, shipping was fast, I'm confident it will do what I need it to do




by:

This 5 wheel lock is perfect. We have a cattle trailer and store it at our farm which is away from our home. This was easy to hook up and I am confident it will prevent someone from using or taking it without my permission. Ordering on line was not only easy with information about the product had a speedy delivery. In the future I will be checking this sight again!




by:

Works exactly as advertised, protecting both the base of the coupler and keeping the coupler from being removed from the trailer. I'm not attaching a picture because the marketing pictures on the website tell it all! Having the option to have both locks keyed the same was great. And, the quick delivery time was fantastic!




by:

The lock fit well on my Ranch King. etrailer came through with some great customer service. The lock was going to take longer to ship than the rest of my order. etrailer split up the shipping without charging me extra, so the rest of my order would arrive on time.




by:

I purchased new gooseneck trailer and needed to secure with some the of lock. Went to web and found this lock system. Looked good so put in order and got it in less than 5 days. Great service! Installed and is better than I expected . Heavy duty and very secure. Very satisfied with service and quality product !




by:

This is an outstanding product ! Was very tight on my WW trailer but with a couple of taps with a hammer; an outstanding fit. The set screw lock works very well. Don't know how they would get the lock off. You must use the washer that comes with the lock. Unfortunately. the hole in the washer is 3/4 " and my set screws are 7/8 ". A little grinding on the hole and everything worked like a champ.




by:

Looks great works good

  • Coupler Lock Recommendation for a Trailer with a Bulldog Gooseneck Coupler
    Yes, the EZ Lock Gooseneck Coupler Lock Combo # BLTL-53-40D2 that you referenced comes with two locks and would work well on your 20k Bulldog Coupler. One lock secures the coupler opening and the other secures the inner tube of the trailer to the outer tube.

  • What Lock Will Work for a Gooseneck Trailer
    In order to choose the correct lock for your trailer, you will need to measure the outside diameter of the coupler and also the outside diameter of the lip at the bottom of the coupler. From there, I have linked the page with all of the gooseneck locks available. If you have the manufacturer and part number of the coupler, I can be more specific with a recommendation.

  • Coupler Lock Recommendation for a Bulldog BX1 Gooseneck Trailer Coupler
    The Bulldog BX1 gooseneck couplers have that handle assembly at the bottom so the lock that would fit at the bottom of the coupler in lock set # BLTL-53-40D2 would not fit. The BX1 series of gooseneck couplers can be locked with a padlock which you could get locally. When the BX1 couplers are in the coupled position, you can place a padlock through the hole as indicated in the picture. The coupler could then not be opened with or without a trailer connected.

  • Coupler Lock for Butler Gooseneck Coupler
    From what I could find online I think the Butler coupler is similar to the Bulldog/Stallion/Superior/TEM couplers so in that case you should be able to use the EZ Lock Gooseneck Coupler Lock Combo # BLTL-53-40D2 for your gooseneck trailer. This comes with a lock for the coupler part and a lock for the set screw as well. Attached is a review video for you to check out.

  • Coupler Lock for an Unknown Gooseneck Trailer Coupler
    Without any identify marks on the coupler itself you would need to contact the trailer manufacturer to determine the brand and model used for that specific trailer. Although yours looks to be a RAM coupler more than anything else. If it is a Ram coupler then you can use lock # BLTL-55-40D.

  • Gooseneck Coupler Lock for 2015 PJ 32 Foot Gooseneck Trailer
    Based on my research, PJ trailers outfit their trailer with a Bulldog gooseneck coupler. 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.

  • Can a Gooseneck Trailer Be Stolen by Dragging it Away with Just the Safety Chains
    They must have been talking about bumper pull trailers because there is no safe or sane way to pull a gooseneck trailer using the safety chains. The trailer would topple over or slide into the thief's vehicle. The best way to prevent someone from trying to drag any type of trailer away by the chains is to make the chains removable if they aren't already and when the trailer is parked store them in a locked storage container on the trailer such as # DZ91717P.

  • Will a Blaylock EZ Lock for Set Screws on Gooseneck Couplers Fit a Square Bulldog Trailer Coupler

Provided the coupler that you have uses set screws to hold the inner tube in place, this lock will prevent anyone from tampering with the set screws to release the inner tube. You could use # BLTL-53-40D2. This comes with the set screw lock, the coupler lock for the bottom of the coupler, and 2 padlocks.
