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

5 out of 5 stars Master Lock 375DAT Snap on Receiver Hitch Lock w/ 5/8"Pin   August 21, 2001

After spending more than I care to mention on a bike rack and a hitch-mounted storage rack I felt I needed to protect them with a hitch lock. The Master Lock 375DAT is for a 2" receiver and replaces a 5/8" pin. I looked at a few bike and hardware stores and found it to be competitively priced on Amazon. It also appeared to be of better quality and lower price than some others I found at a hitch store as well. In assessing the lock I wanted to see how well it performed in three apsects: 1) Fit and ease of putting through the hitch pin opening 2) Ease of locking and opening with hitch attachments on; and 3) Did it make any noise or rattle.

Overall I was more than pleased with the lock. 1) With regard to placement I was pleasantly surprised to find that it slid through my slightly rusty receiver hitch better than any of my existing pins. I think this was because it is a better quality SST than my other pins. I also found the locking mechanism to be easier to lock in place than the conventional pin. Since the locking head is symmetrical I did not have to worry about getting the hole lined up just perfect to insert a cotter pin (also minimized knuckle scraps). 2) It was also easier to mount my storage rack attachment since you approach the lock from the side rather than having to address the cotter pin through the attachment. I had also intended to use with my bike rack which is held in place with a bolt. I forgot the bolt is held in place with a nut welded to the inside of the receiver tube so the lock is unable to go through. Not the fault of the lock, just disappointing that I either have to keep using the bolt or somehow remove to enable the lock to pass through. 3) I was a little concerned that there was some play in the lock and that it might create some noise. The play I noticed helps engage the key in the lock and does not appear to be a problem.

My only complaint is that I wish Amazon carried a version for my other car that has a 1 1/4" receiver which needs a 1/2" pin!

Real nice product. I like the heavy rubber end that covers the lock. Sometimes on these locking bolts, they don't offer a seal on the lock and over time the lock rusts and is hard to work with. Being at the back of the truck, it's going to continue to be wet and the seal should keep the lock from not functioning as it should.

Easy to install and safely secures my bike rack the receiver hitch. Dust cover keeps debris out of the key slot. (Useful feature).

I knew this product would be everything I expected, since it was a Master Lock. I was not disappointed one bit. This product functions beautifully, and it looks like a million dollars compared to the cheesy pins you see on my hitches. I would recommend this product to anybody.

I searched through many hitch locks and felt this one was the best. Easy to use, covering for the key hole, and it has the Masterlock brand behind it. Bravo. A great product.
