BRINKS 673-70001 Commercial Stainless Steel Discus Padlock, Keyed, 70 mm, 4 Pin Cylinder , Black

Got these locks for our storage units. They were cheaper than the ones automatically offered with our units and the same or better quality. I like that they have the black plastic on the outside because it softens the fall if you drop them. It also helps you recognize your lock better because most don't have that. The quality is good and I felt like our stuff was very secure. Both locks are keyed the same, so the 2 keys it comes with work on either lock. Would purchase again!

The place had to cut the one I paid for (with the lost key) when I rented the unit but I had purchased this one for another reason and not yet used it. I happen to have it with me that day as I had not taken it out of my car when it was delivered to the house. This is the exact same lock that was on my storage unit (not the same brand, but the same style of lock), so it worked perfectly. I have it locked on my self-storage unit and have kept one of the keys in a safe place so I if I lose the one on my keychain, I'll have a spare to open it! Good, sturdy lock.

Good lock for trailers but holds water and freezes in the winter

This is a sturdy and well made lock, which will last you as long as you do some preliminary maintenance on it. On the back of the lock is a small hole. Put a drop or two of penetrating oil, or a small amount of powdered graphite in the hole. Let it set for a minute, and then insert your key in the lock and unlock and lock it a few times to get the oil or graphite distributed throughout the locking mechanism. Repeat this every 3 months (or less if you live in a wet climate) and the lock will not fail on you. I used 3-in-1 oil and the lock performs like a champ and has not failed me in the least. Another great feature is that when you have the lock in use, only an electric angle grinder will be able to cut the shackle. I made several attempts with three different size bolt cutters to cut the shackle off the hasp, and could not get a grip on it. Disc locks like this are perfect for securing storage units or other securing mechanisms that are outdoor and exposed since once you lock it, the shackle is not accessible. 5 Stars from us and we're ordering more.

I'm in the process of moving and packing and needed locks for the shipping containers. For the price, they will work for what I need. They do open and close ok, but they just seem rather flimsy and weak. It rattles when shaken, more when in the unlocked position. Yeah, they look sturdy and hopefully they will be a deterrent for people wanting to get inside. If someone really wanted in, I can imagine that these wouldn't be a huge challenge. However, even with a much more expensive lock that really couldn't be defeated, the slider hasp on the door of the container is only so strong, so...my thought is that the lock is about as safe as the latch that it is holding the door shut. As for being weatherproof, it seems to be fine in above freezing weather, but I imagine that it would be a challenge to open if it was full of ice. The pack of four comes with four keys and all keys fit all locks. If you need more keys, it uses the same blank as a 'Master Lock' brand lock. I tried the trick of pulling the key that came with the lock part way out to open and they will not unlock. The key has to be fully in to open the lock. However, when I tried a key from a different lock, a Master Lock padlock, I was able to open this lock with the key partway in. Hopefully nobody else tries this. The key can only be removed from the lock when it is locked. I was hoping to reuse these for my new garage that I'm building at my new place, but I think I'll buy something a little more secure for that application.

Good product

I have four storage units, and now I don't have to fumble for different keys. Each lock is easy to use, and my units are totally secure.

Nice locks, but had to remove the rubber protector to fit on metal building garage doors latches.

Great lock and does its job well. Been using it for a year facing the public side. No issues so far.

He tenido candados de esta marca desde hace más de 20 años y aún siguen funcionando. Muy buena Calidad en el sistema y el material de construcción.

Fantastic product for price.

Compre 3 kit de estos candados el 26 de junio, y ya se están abriendo solos, o no cierran completamente, tengo de esta marca que los compre en otro lugar y funcionaron bien

There's are perfect for my enclosed trailer. Nice and big seem like they are built well. And large enough that you can see them from far so it deters people
