40TRI Shrouded Stainless Steel Disk Padlock with 2-3/4" Wide Body (Pack of 3)

I purchased these a year and a half ago for my enclosed trailer doors and I'm thoroughly impressed with its performance. They are perfect for securing multiple areas, and the shrouded design adds an extra layer of protection against bolt cutters. The stainless steel construction ensures durability and resistance to corrosion, making it ideal for both indoor and outdoor use. The locks feel robust and well-made, providing a sense of security that’s hard to beat. The body is substantial, and the locking mechanism operates smoothly without any hitches. One of the standout features is fact that it retains the key when unlocked which ensures that it cannot be left unlocked. This is a great safety feature, especially for high-security needs. Overall, these locks offer excellent value for money, combining strength, reliability, and convenience. I highly recommend them for anyone in need of a reliable locking solution.

Great durable lock and a lot more affordable than buying it at the home improvement store. Overall a great value for the price paid.

Perfect for securing your trailer doors. Operates smooth and easy. Not my first set. use them on all my equipment trailers.

Very secure and easy to use.

I understand these are made in china which is a disappointment, but that is the way of the good ol USA as of late I reckon. That said, I think they will serve the purpose. Bought them to lock up my large enclosed trailer which has two bar latches on the rear ramp door, and a bar latch on the side door. 3 locking positions, 3 locks. Works out nicely. I didn't experience the issue I read having to jiggle the keys to get them to work. All three of mine seem to open smoothly as I would expect. They seem well built and sturdy even being built in some Asian sweat shop I'm sure, so for $10 a piece I am fairly satisfied. My biggest complaint is't specific to these locks, or Master Lock for that matter. As for most things we need or use today seem to not be made in the USA, even long seasoned USA companies. No wonder it's so difficult to find a good job these days. UPDATE: I still like these locks, but have one complaint. I live in Michigan with freezing temps. I discovered that unless I want to deal with frozen locks on my trailer, that I have to be sure to continually remove the lock and dump water out of it to keep it from freezing inside the lock. This lock does have a couple drain holes, but on my trailer, the latches places the lock sideways, not upright. Water gets in the lock and does not drain in this position. Master needs to have drain holes on all sides so it will drain water in any position. If I don't dump the water out before it freezes, the lock will freeze solid and you won't be able to open it until you thaw it out and dump the water.

Very happy with purchase. Concerned about the thickness of the lock, but it fit well on the storage unit latch. Easy to open and lock with key. Simple concept, but very secure. Feel much safer using this disc lock than just a padlock. Definitely recommend.

Just what we needed and work great

Excellent product
