Video Transcript for Blaylock Industries Gooseneck Trailer Locks - Gooseneck Set Screw Lock - BLTL-51 Review

Speaker 1: Today we're going to take a look at the Blalock Aluminum Easy Lock Set Screw Lock for the gooseneck couplers. Now this coupler lock will help prevent theft of your gooseneck trailer that has an adjustable coupler. It's designed to slide over the set screw. Does include this aluminum bracket. The steel pin with the washer and then the large steel washer. Now this heavy duty bracket will secure around the coupler set screw, prevents removal of the inner tube from the outer tube on your coupler.

The steel pin right here is what will slide through the bracket and under the screw and then you put a padlock through that hole right there on the pin and that'll secure the pin in place.Now the padlock is sold separately. We do sell that on our website and it's listed on this product page as a related product. Now this is made of an aircraft grade lightweight aluminum construction. It's very strong, resists wear and corrosion. Part is made in the U.S.A.

Again, the application is for set screws on most adjustable gooseneck couplers.Few dimensions on this. Overall height of it, it's going to be right at three and one-eighth inches tall. Total width is about two and three-quarter inches wide. Total depth on it is right about two and three-eighths inches deep. The diameter on the steel pin is three-quarters of an inch and total weight of this when it's all put together is about one pound.Basically, what you would do is go ahead and start your pin through there.

Put your washer right on there. Then what you'll do is this large steel washer, this will install onto the set screw of your gooseneck coupler. What you'll do is remove the set screw, put the washer on there, tighten and put the set screw back in, tighten it down, and it'll hold this washer on the set screw. Then what you'll do is, there's these .. You can see these slots right in here, this will slide down right over the washer, on the set screw, and hold it into place like that, and then you'll put your padlock right here through the hole in that pin and that'll hold it right into place so it keeps anybody from removing that set screw and removing your inner tube from your outer tube.That should do it for the review on the Blalock Aluminum Easylock Set Screw Lock for the gooseneck coupler..

This set screw lock is a cost effective measure for trailer theft protection when used in combination with a coupler lock. Most crimes are crimes of opportunity so in removing ease of theft you greatly reduce the risk of loss. 195352

Just as advertised, fits perfectly and should keep the honest honest and at least slow down the crooked. The video installation on the website is very helpful and for what it is worth, I didn't need the included spacer. Have it on a livestock trailer and gooseneck trailer. 193693

Very solid. Multiple holes provide ability to fit and the small ball locked it in place. I had some difficulty attaching one but was able to get it with multiple attempts. I’m confident my flatbed trailers are now secure. etrailer assistance is very helpful. 459528


Comments

The locks I bought have provided the security and confidence because my trailers have been stored in a remote area. My step son even bought one for his trailer. Good product for reasonable price.

This is a great hitch lock, it fits all my trailers, so I ordered another one. I use it on my rv to help secure it as I live in a rural area with. The hitch is easy to use and is adjustable to fit most if not all hitches. 304142

The inside width of this coupler lock is 3-316 inches, so it will not fit couplers that are wider than that.

I like this lock. It is beefy and will be a theft deterrent. It is also simple to install and remove. I found that the _inside_ dimension is 5.5 inches wide - the outside width is 6.5 inches. It just fits the coupler on my trailer. It would be even better if it were painted bright red or orange. 85329

Easy to attach to my 19' travel trailer. It's bigger than I expected and It seems a little loose, but should provide enough deterrence to stop thieves. The Master lock is a perfect addition. 465374

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


Looks like it will do the job, although the smaller model may have been a better fit on my EZ-Loader with 15" tires. I like the locking lug nuts, and that they provide two (I can use the second on my spare). I worried that the multiple key-turns would be a pain, especially if the key is on a keychain with lots of other keys, but it's actually way easier just to spin the knurled knob from the back. 578443

I am using this on a Big Tex 22GN HD and it fits perfectly. I could not find out what type of coupler BIg Tex uses but I asked etrailer and they thought the same thing I did, that it looks like a Ram coupler. If you are looking for a lock for a Big Tex gooseneck look no further because this is the one. 512765

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


The coupler lock is easy to use and should deter the easy theft of my trailer. Because it is designed for both a 2.5" and 3.0" lunette ring, there is some play between the lock and my 3.0" ring, but not enough to impact its intended function. 218177

Thanks for your business and your review, R T. I am sorry to hear about your lock. For ultimate protection, combine this coupler lock with Blaylocks EZ Lock for gooseneck coupler set screw BLTL-51-40D - sold separately, which secures your adjustable couplers inner tube to the outer tube.

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


Great wheel lock. The design and production of the lock is superb. Hopefully it will never be tested but if it is, I'm confident that it will do what it is designed to do. As shown in the picture, it will be used as part of a set of locks to protect our new [email protected] trailer. 207151


Comments

Thanks for the followup. In general Im still very satisfied with the lock. Luckily it hasnt been tested by some unscrupulous person. I have a very secure feeling when using the lock. I guess the only slightly irritating thing Ive found with the lock has to do with the key and lock itself. Compared to all other key locks Ive ever used, this is the only one where the key has to be turned and turned and turned until it reaches the end and the key can be removed. The same happens in reverse when unlocking the lock. You have to turn the key quite a few times to get the lock to where the bolt can be removed and the key can be removed. When youre sitting or laying on the ground putting the lock on or taking it off, this all can be kind of annoying. I wouldnt give up the lock for anything and Im sure it will last longer than Ill have the trailer to which I attach it but a re-design of the locking mechanism could sure help some future customers satisfaction.

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


Coupler lock is not universal in regard to a snug fit. My 2 5/16" hitch is evidently deeper than most because the fit is extremely sloppy. I think the lock is ingenious compared to other styles; however, be aware that to secure the lock as intended by design you may need to add spacers above the lock pin. If the lock remains as a sloppy fit it will be easy to pry off with a crow bar. 161742

This coupler lock part # BLTL-55 is for ram gooseneck couplers. The coupler lock you need is part # BLTL-50 for a Bulldog gooseneck coupler part # BD0289250300.

Good product but not usable on my hitch which is compound locking. Good only for the standard lever lock hitch. 569690

The lock part BLTL-20 is designed for bulldog collar-lok couplers. If you have a traditional style latch lock on your coupler I recommend part # DT25013KA
Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers
$35.95
fastway universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use DT25013KA.

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


I am quite satisfied with the Blaylock coupler lock. It is well made (I appreciate it having been made in the USA). I have both lipped and flat flange couplers on two different trailers, and I only need to lock one at any given time, so I got the one that fits lipped couplers and it will work on either one; if I wanted to be elegant, I would make a shim for use with the flat-lipped hitch just to take some vertical clearance out of it, but that would be merely putting booties on the cat -- it achieves its purpose as it is, and gives me versatility. I like the axial tolerance built into the locking pin because I'm confident it will not hang up, rust, or stick with age and dirt accumulation. 612119

Works well on my goose neck horse trailer. No modifications needed. There is about a half inch of space between bottom of coupler and lock. I was expecting it to fit a little more snug. But seems like it will do the job. Great fast shipping. Will order from these guys again. 142441

I had seen some negative reviews for etrailer and actually hesitated to place an order, but they had exactly what I wanted and their prices were better than anyone else. So I placed an order..... The customer rep was excellent and very helpful. My order arrived in 2 days exactly as I ordered. Great experience.!!! I would certainly buy from them again. 330331

Review from a similar Blaylock Industries EZ Lock in Gooseneck Trailer Locks


This lock system is simple and weather exposure should not be a hindrance for removal when needed. I would like to see the pin made of hardened steel. May get a machinist to fab one up out of a harder Rockwell rating. Painted it Orange and it contrasts very well to the black trailer frame. This is a visual que for those passing by the county road, that the coupling has 'something' on it. The Master lock appears to be of a higher quality the the same design but sold for storage unit use. It may be made by Master but have no way of knowing. The lock operates very smoothly and the stainless body is perfect for outdoor application. A shout out to Jennifer who has been providing excellent customer service from day one. This means I will use etrailer for future trailer needs, thanks to her. Hope this helps others. 398959

still a great solid product. Spray some silicon in the lock about every few months and all works well.

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.
