My first choice in king pin locks didn't work, the wedge from the Reese Sidewinder prevented me from placing the cap all the way up/around the king pin. This Master Lock was my 2nd choice. Good visibility, easy to place, but something about the lock mechanism makes it a bit tricky to get closed. As usual, great service from eTrailer.com! 54407

I purchased this king pin lock for my fiver.......it fits perfectly and is well constructed. I have a Reese Fifth Airborne king pin ......the "wedge" is not an issue. I have purchased many items from etrailer and have been very happy with their service and products. No problem getting questions answered if needed. 335629

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

This is an outstanding product ! Was very tight on my WW trailer but with a couple of taps with a hammer; an outstanding fit. The set screw lock works very well. Don't know how they would get the lock off. You must use the washer that comes with the lock. Unfortunately. the hole in the washer is 3/4 " and my set screws are 7/8 ". A little grinding on the hole and everything worked like a champ. 154955

This 5 wheel lock is perfect. We have a cattle trailer and store it at our farm which is away from our home. This was easy to hook up and I am confident it will prevent someone from using or taking it without my permission. Ordering on line was not only easy with information about the product had a speedy delivery. In the future I will be checking this sight again! 248922

Very happy with service and quality of product. They seem to go the extra mile to be sure you are informed of status of your order ! I placed my order late on Thursday evening and early the next morning Sierra called to explain that they were out of stock on my part number I let her know it was not an issue. I. Still received on the order by Monday!! Thanks 365655

Works exactly as advertised, protecting both the base of the coupler and keeping the coupler from being removed from the trailer. I'm not attaching a picture because the marketing pictures on the website tell it all! Having the option to have both locks keyed the same was great. And, the quick delivery time was fantastic! 71757

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

Review from a similar Blaylock Industries EZ Lock in 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 T@B 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 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

Review from a similar Blaylock Industries EZ Lock in Trailer Locks


This theft deterrent works just fine, super easy to use WHICH MEANS YOU SHOULD USE IT !!! Any theft system is really to stop the person that is not fully prepared to steal something. So using this is 80% of the solution to having your trailer borrowed permanently. Easy to put on and you have to use the disk style lock as this is the only lock that can't be cut into by bolt cutters. Do not use a cheap pad lock or the thieves will go at the WEAK part of the system. 114977

So far so good. When I ordered the item, your operator seemed to want me to have ups deliver it or pay the lower rate of snail mail and they said it would be up to two weeks before I received it. I decided to go the cheaper route of the us postal service and I received my item within only a few days. Just felt like I was being nudged in the more expensive direction. Other than that, I'm happy with said product. Thanks 124606

I done some research about this and similar products and found this product to be the best bank for the buck. made to fit my Bulldog hitch. It is used by folks that sell trailers, I thought that was good enough for me... ordered one with the master lock from e_trailer received in in just a few days as stated as for pricing ...you won't be it by much if any! 160561

lock bracket seems real secure but is a little more trouble than old ,old style ...throw on a lock and your done.
