Most Popular Stainless Steel for 2017 Subaru Legacy

I have not yet had a chance to use this lock as I just got it after getting home from a long road trip. However, I have other MasterLock locks for my flat tow set up. I really like these which is why I got this one to replace an older lock that had some rust issues. I'll follow-up once I get some extended use.

It's easy to lock and unlock, but since I'm only using it with 1 vehicle, I'll probably just leave it attached. Even with the dust cover, I figured it was a good idea to squirt lubricant into the keyhole. Along with the ball-hitch lock I got from etrailer (also excellent) it provides peace of mind.

I have owned two of these for a year now. And both of them are still in excellent shape the one on my truck and camper stay on year round.And neither one of them show any wear at all. And both work flawlessly yet. If you want a coupler and hitch lock keyed the same. I would highly recommend you by this set. And you can't beat trailer price and shipping rates also.

Works great, 1-key fits both locks!

The lock is high quality and I like the fact that it is stainless steel. Works fine with the bike rack (1.5 inch receiver pin easily goes through the rack on a 2 inch receiver). Saves a lot of time over having to bolt things together every time I want to take the bike's out.

Package was opened upon arrival.

I triple checked to make sure I ordered all the right equipment. Everything seems to be 100% right and the quality of the product, B+W triple ball hitch and master lock locking pins, Seem great too. I just opened the box and haven't used it yet but checked sizes are perfect. Trailer always works the first time for me. Thank you etrailer.

Better built than other locks I’ve used. And it handles the bigger 2-1/2” receiver well.

This is probably one of the best stainless hitch locks of the regular through-pin style locks. It installs flush, and uses a solid pin. The locking side is also beefier than most, and sits tighter and deeper on the pin than most other pin locks - making it harder to try and hammer it off, or getting at the pin with a cutting tool. The lock uses large solid ball bearings for the lockup, and a disk style locking mechanism, which is harder to pick without specialty tools. So overall, one of the best regular pin style locks. We towed a 6'x12' that weighed around 6,000lbs from PA to FL without any issues with the pin-lock. We actually had to disconnect our trailer along the way, a few times, and the pin was easy to work with, and the lock really smooth. Don't hesitate to get it.

I purchased this Bulldog pin for my 2015 Yukon with a factory installed hitch. In this application this Bulldog hitch pin fits very well. I selected this pin due to its simple design and the generally compact diameter of the lock cylinder and the pin's beveled head-end. The lock cylinder diameter is import since GM penetrates the nominal 2" ID hitch tube through a steel bulkhead. There is only 7/16" distance between the hitch tube's nominal 5/8" clearance hole edge and the face of the factory bulkhead. Also, the hitch tube is fillet welded to the bulkhead. Thus, both the pin head and the lock cylinder need to have some relief (i.e. the bevel on the pin head-end) in order to clear this external bulkhead weld. Most of the above fitment concerns are overcome by the Bulldog pin's grip length being greater than that listed on the etrailer site (and in their videos as well). Specifically, the grip length is 2-11/16" rather than the listed 2-1/2". See the attached photos. Note that in the first photo the lock cylinder is firmly seated on the ball locking end of the pin. In the photo note that the cylinder is fully engaged and locked, which would not be possible if the cylinder was not fully seated on the pin end. The first photo shows the dial caliper fully closed and properly reading zero. Also note that the GM hitch tube is 2-9/16" square (outside dim.), thus technically a 2-1/2" pin grip length would be inadequate in this application. Since I have a metal turning lathe I was prepared to machine the pin a slight amount in order to make it fit. Thankfully, this was not necessary since the grip length is 3/16" greater than advertised. The pin is Chinese made in "stainless steel". I did test the pin with a magnet and it does appear to be austinitic (high enough in Ni and Cr alloys) since the magnet had no attaction to the pin. I do like that the lock cyklinder has an internal o-ring to help keep out "road splatter". I also gave the lock cylinder a short squit of WD-40. In sum, a well designed rugged product at a fair price.
