    • Narrow end slides over the coupler bracket near the handle
  • Steel pin slides through the bracket to secure the lock to your coupler
  • Stainless steel padlock with hardened steel shackle secures pin in place

After it has been secured, this Blaylock EZ Lock renders your trailer's cast base RAM gooseneck coupler inoperable, ensuring your peace of mind. Simply position the lock around the base of your coupler, with the narrow end of the lock fitted over the coupler bracket near the handle. Then insert the 3/4" diameter steel pin through the holes in the lock and secure the pin in place with the included Master Lock padlock.


For ultimate protection, combine this coupler lock with Blaylock's EZ Lock for gooseneck coupler set screw (BLTL-51-40D - sold separately), which secures your adjustable coupler's inner tube to the outer tube.

loose fitting but should keep honest people from borrowing my trailer 575151

This lock works very well and will hopefully reduce the chance of a stolen trailer. The aluminum construction prevents any rust to maintain the good appearance. 804045

A great quality product that takes away the worry of theft of my goose neck horse trailer. This is my second order. I will continue to use etrailer.com for my all my trailer needs. 736339

peace of mind. Don't have to park a truck in front of it anymore. 728981

After one year, product is still working well. As it is aluminium, there is no issue with rust or corrosion, despite the fact that the trailer sits outside year round. It is also light and easy to attach and remove. In cold and icy winter weather, the lock can freeze up. I recommend using a lock lube spray into the key hole, as well as the small hole in the back of the lock to prevent this. 635959

by:

Have never used one, never had the need until now. One thing I'm not happy with in the product is there being a big gap between bottom of goose neck shaft and plate of product. I feel if someone really wanted to take my trailer they would have the correct tool (s) to cut the hooks into. I hope it doesn't happen. Service was great and shipping very quick. 269745

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

This product has worked great and continues to keep my trailer and contents safe. Again, wish I had purchased years ago

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. 431211

Review from a similar 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


Comments
I remain quite satisfied after a year. I would buy another one if I had a use for two.

Review from a similar EZ Lock in Gooseneck Trailer Locks


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


Comments
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.

I hope the lock never gets put to the test. It arrived quickly and it appears this locking system should work well for anyone looking for a quick theft. It was an easy install and using it is a simple process. 317099

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

Just received this today. It’s extremely sturdy and getting a bolt cutter anywhere on this hitch lock looks impossible. I’m so far very impressed 698912

Ask the Experts about this Blaylock Industries Gooseneck Trailer Locks

  • 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...

  • Gooseneck Coupler Lock for Kaufman Trailer
    The correct lock for your Kaufman gooseneck trailer is the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-55-40D (which I confirmed with my contact at Kaufman). If you'd like a lock for the set screw as well then you can use the kit # BLTL-57-40D2 instead which includes both the lock for the coupler section and the set screw.

  • Recommended Coupler Lock for Big Tex Gooseneck Trailer
    I was not able to locate specific manufacturer information regarding the couplers that are used on Big Tex Gooseneck Trailers like what you have. With that being said, they do look very similar to the Ram Gooseneck Coupler # GCSQTW-30008 that you mentioned, with its square tube design and crank. If you find that this is what you have, I recommend the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-55-40D. This coupler lock is designed specifically for Ram gooseneck couplers and features...

  • Lock for Ram Gooseneck Coupler With Round Tube
    The InfiniteRule Hitch Lock is designed for goosenecks with a 4" round outer tube, and the RAM goosenecks have a 4-1/2" round outer tube like the Ram Gooseneck Coupler # GCPN-25008. For the most security I recommend the Blaylock EZ Lock Gooseneck Coupler Lock Combo - RAM Gooseneck Couplers # BLTL-57-40D2. This has a coupler latch lock and set screw lock and comes with a pair of padlocks for the best way to secure your gooseneck. You also have the option of getting the coupler...

  • 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 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.

  • 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...

  • 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. With multiple trailers you will probably be best off using a multi-fit lock.
