Video Transcript for Blaylock Industries Gooseneck Trailer Locks - Gooseneck Set Screw Lock - BLTL-51-40D Review

Today we are going to review part number BLTL-51-40D, this is the Blaylock easy lock for the setscrews on a gooseneck coupler. It includes the master lock the master lock padlock. This part will include the bracket or cover that goes over the setscrew, the three-quarter inch diameter steel pin which will slide through the back bracket and under the setscrew. It will include this washer, which Ive already pre-installed on the setscrew and includes this master lock stainless steel padlock. Now this lock will help you fight back against trailer thieves, its a simple yet effective way to prevent theft of this inner tube of your goosenecks trailer coupler and it does have a simple installation. Basically, what Ive done here already, is you just remove whatever setscrew you want it to lock, put the lock on.

If you remove the setscrew with the lock not attached, and then you install this washer that comes with the lock set onto the setscrew behind the lock nuts. When you tighten down and its in position and then you want to lock it down with the lock nut, youll just tighten this lock nut and it will secure this washer securely on the setscrew. Now with that installed, if you look at this bracket, this heavy duty bracket, aluminum bracket, it has a groove cut right in it here that will allow it to slide over this washer and then cover the setscrew. Youll take this three-quarter inch diameter steel pin, it has a three-eighths inch hole in the middle for the padlock to go in. this will basically go through the bracket, under the setscrew and through the other side.

What you want to do is take this padlock; this is a stainless steel master lock padlock. It has a hardened steel shackle, which will secure this lock to the coupler. It has a shielded shackle design, which will prevent access with bolt cutters and its resistant to wear and tear and corrosion. It comes with two keys and they can be keyed to match your other Blaylock coupler locks that you might have on something else on your trailer. Basically, if we open this and then we just turn it until we can get the hole to line up, there we go.

Once we get the padlock through the pin, just pull the keys out, that will be locked into place. As you can see, the pin cannot be removed and does not have any access to get through that setscrew. Once this has been installed, this lock will render the inner tube of your trailers coupler inoperable, gives you peace of mind. This part is made in the USA. Now with this lockset does come with the included master lock padlock.

If you already have a padlock that you can use you can just buy the lock set, which is part number BLTL-51, that comes without the padlock. Theres also another lock that you can use with this that will actually lock on to the bottom of the gooseneck coupler, which will prevent access to the latch. That part number would be part DLTL-50-40D with both locks on there, that will help secure your gooseneck coupler. Now I do want to give you a few measurements. Lets take the lock off, there we go, take the 0:03:45 inaudible out, and well remove this off there. Basically, a few dimensions on this. the width is going to be two and three-quarters. Ill just give you the depth of this, its also going to be two and three-quarters. Now the height of it is going to be three inches and the dimension on the inner part, which will go over the setscrew, itll be one a half inches. This pin again was a three-quarter inch diameter pin. That should do it on review of part number BLTL-51-40D.

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. 142439

Used on my Wells Cargo 16' enclosed trailer. I touched mine up slightly with a grinder because it was a tight fit and it's on perfectly now without being too tight. Good solid construction. 694061

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

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.

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. 74643

First of all I want to say it is wonderful working with a company that actually cares about how their products are viewed by customers! Thank you. As for the lock itself, I am very happy with it. It is so easy to install and disconnect. I feel very confident in its ability to protect my trailer from theft.
