  • Coupler lock helps deter theft of your gooseneck trailer that has an adjustable coupler
  • Heavy-duty bracket secures around coupler's set screw to prevent removal of inner tube from outer tube
  • Steel pin slides through bracket and under screw
  • Stainless steel padlock with hardened steel shackle secures pin in place
  • Aircraft-grade, lightweight aluminum construction is strong and resists wear and corrosion
  • 2 Keys are included
  • Made in the USA

  • Application: set screws on most adjustable gooseneck couplers
  • Overall dimensions: 4" long x 4" wide x 5" tall
  • Pin diameter: 3/4"
  • Weight: 1-1/5 lbs


After it has been secured, this Blaylock EZ Lock ensures that the inner tube can't be removed from the outer tube of your adjustable gooseneck coupler. Simply position the lock around the set bolt, insert the 3/4" diameter steel pin through the bracket and under the bolt, and secure the pin in place with the included Master Lock padlock.


An additional coupler lock (BLTL-50-40D or BLTL-55-40D - sold separately) is available to prevent unauthorized access to the coupler latch.

A++ Exactly what I was looking for Set Screw Sleeve Lock. Friendly great professional very knowledgeable staff. Thanks



by:

This lock was exactly what I needed, and gives me peace of mind knowing that my trailer is secure. When I called to order the lock, Kyle, was courteous and helpful. I received it exactly when he said I would. This is a great business to support, and I highly recommend them.



by:

Sturdy and solid assembly, easy to install. This should be great security from those who simply remove the pin an install there own lower unit...and disappear with your trailer.



by:

Excellent lock.



by:

Had to grind the washer hole opening to enlarge it so that it would fit the bolt on my gooseneck horse trailer. Looks nice and tidy and like it will send a thief on to the next one. Shipping was fast and service was excellent.



by:

The product works well as a strong theft deterrant. etrailer was the best price at the time of purchase and their service was excellent.

I would recomend etrailer for any of their products.

Works as advertised. Provides security and peace of mind.

very good product gives peace of mind when trailer is parked

Hello, I received my new wheel promptly. I appreciate the communication from Becky B. She gave me a direct answer to my question asking if the wheel was in stock. The last time I ordered a wheel that wasn’t in stock I did not receive a direct answer that the wheel was on back order even though I specifically asked if that particular wheel was on back order.

Thanks for the communication



by:

Easy to install and the aluminum/stainless steel construction should be long lasting.

great fit and function

The lock fit my Kaufman gooseneck no is sue.



by:

It is a well thought out product. The lock device for the King Post height adjustment cap screws fits nice. However, the main locking slug for the ball hitch doesn't fit my trailer like it is supposed to. I have a Kaufman trailer and I'm not sure what brand of post they use. The guide tab for the ball lock D-ring is in the way of the Blaylock pin. I am able to rotate the locking device 180 degrees and install it that way. It's a bit sloppy but it will impede a potential theft.
I also fear the longevity of the padlocks. I can see them rusting if left out in the weather for too long. I keep my trailer tarp on when not in use and also flood the padlocks with WD40
I know it is impossible for a "fits everything" product. I think Blaylock would serve themself well if they did research and list all trailer brands that will fit or not fit their product and perhaps, have an alternate choice.
I do recommend looking into this product if anyone is thinking about securing their trailer.



by:

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



by:

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.



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.



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 !!!!

  • 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. You would need the # BLTL-53-40D2 or # BLTL-57-40D2. The...

  • What is the Width of the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289650300
    The inside width of the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289650300 is 3-7/16" while the outside width is 4". If the inside width of your outer tube is about 3-1/2" then this coupler adapter won't fit. All of our other square inner tubes have the same 4" outer diameter. You may need to swap out your whole coupler for an option like part # BD0289590300 which is the whole adapter; inside and outside tubes. You can lock the king pin with part # e98896 and the inner...

  • Lock For Gooseneck Coupler With Cable Release & Lever
    Hi Evon, Appreciate the photo, thank you, and while there is a lock option, the part number you mentioned won't work on your gooseneck coupler with the handle. There isn't a similar type of lock for the bottom of the coupler, the best have is a lock for the set screw, the Blaylock EZ Lock for Set Screw on Gooseneck Coupler # BLTL-51-40D.

  • Recommended Blaylock Gooseneck Coupler Lock
    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. The Blaylock EZ Lock Gooseneck Coupler Lock, part # BLTL-55-40D is designed to fit RAM Gooseneck Couplers. This lock has a wider bracket for the RAM Coupler. If you have a Bulldog, Stallion, Superior, or T.E.M. Gooseneck Coupler the correct lock for you is part # BLTL-50-40D. This lock has a narrower bracket feature. My contact...
