Video Transcript for Blaylock Industries Gooseneck Trailer Locks - Gooseneck Base Lock - BLTL-50-40D Review

Today were going to review part number BLTL-50-40D. This is the Blaylock Easy Lock Gooseneck Coupler Lock with the included master lock padlock. Now, this part will come with the base, the three-quarter inch diameter steel pin and the Master Lock padlock that is used to lock the pin into place. You can fight back against trailer thieves by using this rugged Blaylock Trailer Coupler Lock. After its been secure this lock will render your trailer with gooseneck coupler inoperable, which will ensure peace of mind. This part does fit most gooseneck trailers with Bulldog, Stallion, Superior, and TEM couplers.

The way this would work, this heavy-duty bracket will secure around your trailer couplers base at the narrow end, which is this part right over here. It will fit over the coupler bracket near the handle on the gooseneck coupler. Then right here on this end there are two pinhole positions which will allow you to slide this three-quarter inch diameter steel pin through and ensure a tight fit around the coupler. The Master Lock padlock will secure this pin in place. This is a stainless steel Master Lock padlock.

It has a hardened steel shackle which will secure the pin to the lock. It is a shielded shackle. This design will prevent access with bolt cutters. It is resistant to wear and corrosion. It does come with two keys, and they can be keyed to match your other Blaylock couplers that might use this type of lock.

This part is made in the U.S.A., and the base here is constructed of an aircraft-grade lightweight aluminum construction, which is strong and resists wear and corrosion. This three-quarter inch diameter steel pin is included also. Just want to give you a few dimensions on it. The overall length on this is going to be right around 12 inches. The overall height is going to be right at about five inches.

The width at the widest part is going to be right at about seven inches. I do want to give you an example of this on a gooseneck coupler, and I happen to have an example here of the inner tube that goes in a gooseneck coupler. This will be the base that this will lock onto. Basically how this would operate is you would take this lock and take this narrow part right here, this side right here, and this will go on the side where the handle is. Here is the handle side of the gooseneck coupler. If you take this narrow end and just put the hooks over the one side of the coupler base, bring the lock around. Youve got your two pinhole positions. You would take the pin that will give it the tightest fit. In this case it would be the bottom one. Wed run this pin through and as you can see that will give you your best fit. Once this is through you take the included padlock, run it through the pin and that would lock this pin into place on the lock. As you can see, this lock will keep anybody from being able to put their gooseneck ball into this inside of the coupler. It will prevent anybody from attaching and driving off with your trailer. We do offer this padlock is sold separately, which is part number ML40D, and if you already have a padlock and you would just like this base and the pin without the padlock we do sell that, and it would be part number BLTL-50. That should do it for review on part number BLTL-50-40D.

  • 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
    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...

  • Gooseneck Coupler Lock for a Sundowner Trailer
    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...

Just select keyed alike from the drop down box on the product page then choose how many you want in the quantity box.

  • 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.

  • 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. 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.

  • 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.

    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...

  • Coupler Lock for RAM, Bulldog Style Gooseneck Couplers
    The Master Lock Trailer Coupler Lock # 377DAT is designed to fit trailer couplers that are towed with a rear hitch, not a gooseneck hitch. For a gooseneck coupler lock, you would want # BLTL-55-40D for RAM gooseneck couplers or # BLTL-50-40D for Bulldog/Stallion/Superior/T.E.M. couplers.

  • 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.
