Amazon.com Product Description

Keep that unattended trailer locked and secure with this snap-on hitch lock from Master Lock. The unit features a 5/8-inch, bent pin that slides into the trailer's receiver tubes with ease. The pin attaches to the lock so it can't be removed without one of the two included keys. Fitting 2-inch square receiver tubes, the lock is protected from the elements by Master Lock's Weather Tough seal for years of reliable trailer security. A stainless steel body and solid brass cylinder core resist corrosion for smooth operation and optimal security. And, an attached, plastic lock cover keeps moisture and road debris out of the keyhole for added protection. This Class III/IV lock also features a precision pin tumbler mechanism that resists picking. The unit accepts K1 key blanks for making additional keys. --Brian D. Olson

Worked as it was supposed to but after the first winter, I guess salt somehow got past the cover and I couldnt get it unlocked, will not buy another one of these as long as I live somewhere where it snows.

AVOID Complete junk, corrodes in months!, 2010-02-07;   By: D. C. Rennie(Boston MA)
I bought this back in July 2008. I went to take it off in Aug 2009 and it was so corroded and rusted the lock was frozen in place. I had to have it cut off at a welding shop. I would avoid this lock!

Amazon Needs To Update, 2009-10-02;   By: M. Azzaro(USA)
Do not buy this pin with the combo offered on the bike rack. As I found out, to late, the pin offered by Amazon is the wrong pin and will not work. The bike rack manufacturer uses a specifically designed bolt style pin making this pin unusable. Wait until you get the bike rack and if you do not care for the pin supplied you can order a locking bolt pin from the internet or pick one up at u-haul or someplace else that deals in hitches.

No rust, no issues, no complaints., 2009-09-25;   By: Read Rover(FL)
I waited for 5 months to write this review as I'd noticed that another reviewer had experienced some issues with rust after only 4 months. This hitch lock lives in Florida near the water where it is exposed to high humidity and high salinity environments every day. If it were going to have rust issues, this environment would have made an ideal incubator. Thus far, no rust. No issues at all, in fact. It was easy to install, tucks away unobtrusively, the cap protects the lock interior and it does the job it was designed to do very well.

Important will not work on Swagman bike rack, 2009-09-20;   By: Christopher Fields(reno, nv)
Amazon recommended this as part of my order of the swagman bike carrier. I did not read the reviews from other people before I bought this lock for the carrier. It will not fit at all with the swagman. As I write this, Amazon still has not removed it from its recommeded list for this bike carrier. Do not add it if you plan to buy this carrier which by the way, wonderfull bike rack for my truck.
