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

It worked on my one trailer, but on my other trailer it wouldn't fit on the king pin far enough to put the pin through the bracket 394835

I'm the owner of two boats which I trailer to and from the salt water. I have used the Master trailer hitch lock for security purposes and I believe it the be the best choice for theft prevention. The way this lock is designed there is no way to easily cut it off if installed properly. It will also withstand the salt water environment. Until I find a better pruduct this is the lock for me. I bought two locks keyed alike which is really helpful at just [...] each lock. 86910

Of all the locks I have bought throughout the years, and all of the Master locks I have bought, this was the most disappointing !!!! Right out of the box this was CHEAP !!!! Being a multi-piece shackle it loses seems to lose its strength and in the open position it is like a 3 piece wet noodle. It seems all a burglar would need is a large pair of pliers to grab it and twist it right apart. I will be sending these right back in less than 2 hours of receiving them !!!! My search continues for locks for my enclosed trailer. Mr. G 33398

This review is going cover all the items in my recent order. As with every past order I placed with Etrailer the customer service continues to be excellent. Items ordered are high quality and the pricing is competitive with any vendor on the internet. The internet site is very easy to navigate and use of reviews of products is extremely helpful. I am a past customer and will remain a faithful customer from this day forth. Thanks Etrailer for the great variety of products and the Super Fast Shipping. 167768

These are the locks I have been looking for in the Chgo area. Most marine use inventory is quite limited in the Chgo area this time of year. I will be using these locks on my hitch, trailer and boat accessories. I am very pleased with the quality, pricing, speed and ease of doing business with etrailer.com on these purchases. I highly recommend them for trailer equipment purchases. 60328

This lock is a ton stronger than others locks I have bought with the beveled ridged pin and slide on lock, they just bend too easy. This one sure won't do that. Great lock, great price and fast shipping. 255403

Product is to replace a lock I lost. I impressed with the speedy delivery from etrailer.com but perhaps it's the proximity to my location. I recommend them. BW 44290
