Blaylock Industries Gooseneck Trailer Locks - BLTL-53-40D2

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
  • Keyed-alike option - select "Keyed Alike" to order multiples of these locks keyed alike or to key the same as other Blaylock locks that use the 40D Master Lock padlock
  • 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.

Video Transcript for Blaylock Industries Gooseneck Trailer Locks - Gooseneck Base Set Screw Locks - BLTL-53-40D2 Review

Speaker 1: Today we're going to be taking a look at the EZ Lock Gooseneck Coupler/Lock Combo. This is going to work with Bulldog, Stallion, Superior, and TEM gooseneck couplers. This is going to be a really good way to prevent any tow away theft of your gooseneck trailer. It's going to lock not only your coupler, so that no one can attach to your trailer, but also your set screws, so that no one can remove the inner from the outer tube. It's going to come with the two padlocks to secure those down. The coupler lock will fit with, again, most adjustable Bulldog, Stallion, Superior, or TEM couplers.The coupler latch just fits around the base of your trailer coupler to prevent access, so no one can get that screw undone.

It's going to hit that bracket. You just have to slide this in and around there, and then it secures at the back with that stainless steel pin that slides through and then a padlock on the end.The set screw is going to be similar. You'll need to have this fender washer installed on your set screw. That's just going to slide onto your lock. The pin slides through the bracket and then the lock secures into the hole on the pin.

It does come with a spacer to take up the gap there to make sure that that's going to be nice and snug in that coupler or in that lock housing.Again, the padlocks are going to be stainless steel. They can be ordered with a key to like option. You'll just have to select key to like in order to get multiples of these locks or to get the same as other Blaylock's that use the 40D MasterLock padlock. It comes with two keys per lock, four total. You can keep one set at home, one in your vehicle.

You'll have plenty to get in and out of these locks.The construction is going to be made of a lightweight, aircraft grade aluminum. It's going to be strong and also resist wear and corrosion. That goes for the coupler lock as well as the set screw lock. The dimensions on the coupler latch, it's going to be about 11 inches from front to back. It will be 6 1/4 inches wide up at the top and about 6 1/2 at the bottom.

It's also going to be about 4 1/2 inches tall. As far as the dimensions on the set screw lock, that's going to be 3 1/8th tall by 2 11/16th inches wide. Flip that around the other way, so you can see it correctly. It's about 2 11/16ths there. It's going to be 2 5/16ths inches tall. The pin diameter for both the coupler latch and the set screw latch are going to be 3/4 of an inch.That's going to do it for our look at the EZ Lock Gooseneck Coupler/Lock Combo.

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. 608985

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. 608631

This thing might as well have tracks and a turret because it's a tank. It's a great purchase that gives you peace of mind. Get the combo deal because it locks both the coupler and the drop tube to foil all but the most dedicated and equipped thieves. 438074

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. 293162

Ask the Experts about this Blaylock Industries Gooseneck Trailer Locks

Do you have a question about this Gooseneck Trailer Lock?


  • Why Cant a Regular Gooseneck Coupler Lock be Used on a Reese Goose Box Adapter
  • The Reese Goose Box adapters such as # RP94716 don't have a straight down-tube like a traditional gooseneck coupler so the locks for regular gooseneck couplers, such as # BLTL-53-40D2, will not work. They cannot grab onto the coupler like they are supposed to. To secure the trailer a wheel lock such as # WI490 or # RA-25 or something similar is recommended instead. I have linked some videos on these locks for you.

  • Recommended Keyed-Alike Locks for Multiple Trailer Hitches
  • I do have a few possible solutions for you, however we do not currently offer a product that would allow you to have everything in your system keyed-alike. Depending on the tow vehicles you drive, I recommend looking at the BOLT Trailer Hitch Receiver Locks like the # BL7023584. These are vehicle specific pin locks that, depending on the tow vehicle you are using, can actually be coded to your ignition key - so you will always have the correct key with you. Since you do have multiple...

  • 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 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.

  • 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.

  • 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...

  • 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...

  • 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...

  • 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. But that is not going...

  • Coupler Lock Recommendation for a Gooseneck Trailer with Bulldog Coupler
  • The EZ Lock Gooseneck Coupler Lock # BLTL-53-40D2 was specifically designed to work with Bulldog gooseneck hitches so it should work well for you. Otherwise you will need to go with a wheel lock like the part # WI490.

  • Yes, the EZ Lock Gooseneck Coupler Lock Combo part # BLTL-53-40D2 will work with a Bulldog gooseneck coupler. I have attached a photo of the above lock installed on a Bulldog gooseneck coupler for you as well. The EZ Lock Gooseneck Coupler Lock Combo is made of a rust proof aluminum. It comes with two locks, one for the gooseneck coupler and one for the inner tube. Each lock comes with 2 keys each for a total of 4 keys. The locks are also made here in the U.S.A.

  • Lock Recommendation for Goose Trailer
  • Since I do not know what specific coupler you have the best recommendation I can make is to use a wheel lock that will also trailer but would not have compatibility issues that a gooseneck hitch could. The # RA-25 would work well for this. I attached a review video for this for you to check out as well.

  • 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.

  • Longest Available Gooseneck Hitch Pin Lock
  • The longest locking hitch pin we have available for gooseneck applications is the InfiniteRule Hitch Lock # 34065041, which features a shank/inside pin length of 4-3/8 inches. Its overall length is 6-3/4 inches. Your best option is likely with a latch lock like the EZ Lock # BLTL-53-40D2. This particular lock is designed specifically for Bulldog, Stallion, Superior, and T.E.M. gooseneck couplers.

  • Will a Blaylock EZ Lock for Set Screws on Gooseneck Couplers Fit a Square Bulldog Trailer Coupler
  • The Blaylock EZ Lock, # BLTL-51, should work fine with a square Bulldog gooseneck coupler like # BD0289800300, # BD0289600300, or # BD028900. 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.
