  • Heavy-duty bracket fits around the base of your trailer coupler
    • Narrow end slides over the coupler bracket near the handle

    • Padlock (sold separately) is required to secure pin in place

by:

Very well made, seems heavy duty but the weight isn’t bad since it’s aluminum nice fit on my hitch.



by:

Excellent lock for gooseneck trailers. I’ve had mine for over a year. Have purchased several more since this one for other trailers.



by:

It fits on a Bulldog coupler quite loose no matter what way you install it. The way I am using it the lock is tighter but like every other lock system out there it only to keep the honest people honest. If someone wants something they are going to get it.



by:

Perfect fit to the hammerblow gooseneck hitch. etrailer was significantly lower in price when compared to others.

100 functional and worth every penny.



by:

Have used these for years, no problems. Easy to use and light weight, and they work for me



by:

very easy to install and fits like a dream!
built
rugged enough where i dont think anyone could pry it off
just what i was needing



by:

We use this lock all the time. It works great.



by:

Works great to make the trailer appear secure. It is only as strong as your lock but that will deter most of any theft. Really happy with this.



by:

I tried this on my Bulldog coupler. It had a very loose fit and the retaining pin barely hooked over the base of the coupler. A good wack with a heavy hammer would easily have dislodged it. A photo on another review shows the poor fit.



by:

I have two goose neck trailers with the Bull Dog type hitch. This product fit one of them. There must have been some design change on the hitch. The newer of the two hitches is about two years old. The older one is going on 10 years and there is a difference. We will continue to use this on the newer trailer.



by:

I have been looking for gooseneck lock. Your work reel good



by:

I have bought several items from this company and the service is excellent. Ships same day or next and the products have been of quality. I love the Blaylock line of locks for trailers. Have one for my pull trailer and 3 for dump trailers. I also have the EZ Jack and Wheel Chock. What a great idea!! I have 3 dump trailers and always having flats. This is so easy to drive upon and then change tire and no having to get a jack out, crawl under the trailer and fix.



by:

Exactly what I was looking for, I wished it fit just a bit snugger, it very loose fitting, but hopefully it will keep my trailer from getting stole.

Im still using it, its working fine, thanks for checking back



by:

The Blaylock BLTL-50 gooseneck lock fit perfectly on my Bulldog coupler. I used a discus padlock in the pin. Gooseneck lock is made very well; the fit and finish is excellent. Now I don't have to be concerned about my livestock trailer being stolen from my farm.



by:

Have used E Trailer on numerous occasions to order items needed for my trailers. Always receive my order promptly. The BLTL-50 is great for locking my gooseneck trailer. Once installed it is a little sloppy but I just cut some think rubber and placed in between gooseneck and lock and it is just fine.



by:

This gooseneck coupler lock works great. Depending upon your coupler style, you may need to cut off the tabs a little bit to get a proper fit. It's an easy and quick modification.



by:

Item was exactly as described. E-trailer called to let me know the product was on backorder; appreciated that a person actually called to let me know. Items arrived prior to estimated delivery date.



by:

Did not fit my bulldog trailer coupler.

I will have our Customer Service team reach out to you.



by:

I really like the gooseneck coupler lock. I will recommend it to others. It's sad that we have to lock trailers to keep people from driving off with them, but I'm happy to have some added protection.



by:

easy to use
well made and sturdy
out
in the elements for a year now with seemingly no ill effect



by:

This lock did not fit my gooseneck hitch. The description said it fits, but it did not. I gave it to a friend to see if he could use it...



by:

The product is awesome! Light weight, easy to use. Once ordered, the product shipped quickly, and I do not have any worries about my gooseneck trailer being stolen!



by:

A great product. I was using a masterlock product which was awkward,didn't always lock and was easy to defeat. This has two holes to choose from for a great fit, and is solidly built. I bought two and HIGHLY recommend this product.



by:

etrailer sent me the wrong lock now I have to send it back

It works. Needs more adjusting holes for the locking pin. The outside pin works on mine, little loose though. The inside pin won't work on my titan

  • Parts Needed for Keyed Alike Lunette Ring, Gooseneck Coupler, and Hitch Ball Coupler Locks
    To add locks to your trailers that have the Lunette Ring Couplers (which connect to pintle hitch receivers) you will want to use 2 of part # BLTL-60. For your gooseneck hitches you will want to use 2 of part # BLTL-50 for Bulldog/Stallion/Superior/T.E.M. Gooseneck Couplers or part # BLTL-55 for RAM Gooseneck Couplers. To lock the set screw you will want the Blaylock EZ Lock Set Screw Lock on Gooseneck Coupler # BLTL-51. For the traditional trailer hitch ball couplers you will want to...

  • Lock Recommendation for a Bulldog BX1 Gooseneck Coupler
    The Bulldog BX1 gooseneck couplers have that handle assembly at the bottom so the # BLTL-50 would not fit. The BX1 series of gooseneck couplers can be locked with a padlock like the part # 141T. 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.

  • 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.

  • Padlock Compatible with Blaylock EZ Lock Gooseneck Coupler Lock
    There is a padlock that is compatible with the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50, but if you were referring to the Master Lock Shrouded Padlock # 37DAT, it will not fit because the Coupler Lock has a 3/8 inch diameter hole for the padlock to fit and the Shrouded Padlock fits openings of 1/2 inch diameter or larger. The padlock which is compatible with the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50 is the Master Lock Stainless Steel Padlock with Shielded Shackle #...

  • Replacement Pin Recommendation for a Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50

  • Determining Type of Coupler Lock Needed for Gooseneck Coupler
    The physical difference in terms of appearance between various well-known gooseneck coupler manufacturers is hard to spot because they all are fairly similar. The biggest difference comes with the width of the coupler flange. The best way to determine which coupler lock is needed, the Blaylock EZ Lock for Bulldog/Stallion/Superior/T.E.M. # BLTL-50 or the EZ Lock for RAM # BLTL-55, is to take a quick measurement on your coupler's flange width. The EZ Lock # BLTL-50 has a width between...

  • 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. If you want the coupler lock, the set screw lock, and padlocks...

  • Could Blaylock EZ Lock Gooseneck Coupler Lock Fit 2021 Lamar 14k Dump Trailer
    Most likely yes, but you'd need to verify that your 2021 Lamar GDL831627 has a Bulldog, Stallion, Superior, or T.E.M. coupler for the # BLTL-50 to ft. You'll need the padlock part # ML40D to go along with it.

  • Coupler Lock to use with Gen-Y Fifth Wheel to Gooseneck Lock for Lippert 1116 Pin Box
    Gen-Y actually makes a coupler lock for their cushioned 5th wheel to gooseneck adapters like the # GY48FR with the lock part # GY89FR. There's a chance the Blaylock part # BLTL-50 could work but at this time it's not been tested so we can't say for certain.

  • Will the Blaylock EZ Lock Gooseneck Coupler Lock Combo Fit Bulldog Gooseneck Coupler
    The EZ Lock Gooseneck Coupler Lock Combo # BLTL-53-40D2 will work well for your Bulldog Gooseneck Adjustable Coupler # BD0289250300. Unfortunately we have not yet had a chance to test the lock on a 0289340317 coupler to be sure of the fit. I have attached a diagram with the dimensions of the coupler lock in the # BLTL-53-40D2 combo for you to compare with your coupler. This is the best way to ensure the coupler lock with fit with your 0289340317 Bulldog coupler. I have also attached...

  • Will Blaylock Coupler Lock Fit B&W Gooseneck Coupler
    The B&W gooseneck couplers come in 2 different setups; the Defender parts # BWGNC4250 and # BWGNC4251 as well as the Extend-A-Goose # BWTEXA4200. The Defender couplers have built-in locks and come with keys while the Extend-A-Goose is lockable if you install a padlock in the handle bracket (see attached photos). Because of this the design of the couplers won't fit with a standard coupler lock like the Blaylock # BLTL-50 you're looking at. If you have a different coupler please let me...

  • Recommended Coupler Lock To Fit on a Bravo Gooseneck Trailer
    I contacted our representative, Blaylock, to inquire about this EZ lock coupler # BLTL-50 working with Bravo products. He wasn't certain if it is compatible but he provided me measurements. See diagram to the right. The short bed extender by Pop Up SB series you have works with most Bulldog, Stallion, Superior, and T.E.M. gooseneck couplers. Other couplers may work but I recommend using the diagram to the right to view the measurements of the Blaylock EZ lock coupler. We also sell this...
