Amazon.com Item Description:Keep your trailer safe from thieves three different ways with this lock set from Master Lock. This keyed-alike set protects boat trailers or any 2-inch receiver trailer, from tow-away theft. The set includes a coupler lock that fits 1-7/8- and 2-inch ball diameters, a receiver hitch lock for 2-inch Class III / IV tubes, and a coupler latch lock that fits most standard latches. The triple protection secures the trailer in-tow and when it's just sitting unattended. Plus, all the locks are keyed alike, so you only have one key to keep track of. Premium quality, with solid brass cylinder and case, hardened steel shackle, the set features a pick-resistant 4-pin tumbler for optimal security. An internal O-ring and water-tight cap keeps out water and dirt for years of smooth performance. The set comes with a 10-inch carry case.

Latch Lock is Different
The latch lock pictured is not the one you get in the box. It is the sub $9.00 lock here:Master Lock Adjustable Coupler Latch Lock, Stainless Steel #2847DATSC The one in the picture looks like the ~$19.99 lock here: Masterlock 1475DAT Lshkl Brbll Lk 7/8"" " or the ~$14.00 one here: Coupler Latch Lock By Master Lock Company
I would have given this product the five stars if it had come with the pictured items. A bit of a bait and switch...

Great Product, but not exactly as pictured.
This is a great product. Very well constructed. I was able to use all the components, but the latch lock was not the one pictured on the site. Which is why I only gave it 4 stars. I brought this misleading info to the attention to Amazon, but they are yet to fix it. Master Lock's site should have the right photo for the 3774DAT.

Useful set
I have found two of the three locks in this set useful. The hitch lock did not fit on my trailer. Thus this only gets four stars.
