Proven Industries 400XL Puck Lock Set - 3-Pack, Hidden Shackle, Blue | Hidden shackle configuration, 6061 aluminum construction, keyed alike cylinders, 3-pack security set, USA-made.

Best trailer locks I've ever had. They are easy to misplace because they don't have a clow or hook. Snook sleek and a great looking finish.

I love this puck lock. It was easy to install, built to last, value and security for our trailer is worth every penny. We decided to purchased security locked bc we had our trailer stolen and got it back without our personal belongings. I did research and found this one. Worth peace of mind and knowing that our trailer will not get stolen again. I highly recommend it.

These are very nice locks. They fit well and have a hard to pick key slot so I feel like my trailer is safer from thieves than with other style locks I've used in the past.

Well, it’s in their name! These are built like a tank. Keys all match for the three locks. MADE IN USA!! I had the Chinese version in my cart for $100 less. But the more I thought about it, the more I wanted to buy American! So I purchased these instead. Great American made product!!

This puck lock set feels very solid and heavy-duty. As soon as you pick it up, you can tell it’s made with good materials. It’s easy to install and it locks into place firmly. I like that it covers everything cleanly and doesn’t rattle or move around. I bought it to secure my trailer and I feel a lot better leaving it parked now. It looks and feels way stronger than the cheaper locks I’ve used before. So far, very happy with it

I can’t say enough about this exceptional product and Proven Industries' service. They are customer centric, and their service surpasses all others by comparison! The quality is truly above and beyond, exceeding all my expectations. The product is well-designed, reliable, and packed with features that make it a top notch. I reached out to customer service with an inquiry about previous purchase and the possibility of matching all locks. They sent key cylinders for my previously purchased locks, which are now keyed the same as these. The customer service team was incredibly responsive, going out of their way to ensure I had a seamless experience. From start to finish, everything was top-notch. Highly recommend Proven Industries to anyone looking for these amazing lock products!

Great design but a constant headache. At first all three locks worked great, then one the key wouldn’t go the whole way in, another would unlock but only release key if off trailer snd relocked. Now it is a constant struggle to get the key in all three snd unlocked. Nothing like panic when you can’t unlock your trailer doors. I have same lock design on trailer coupler, it has different key snd works 100% of time. Lubrication doesn’t help.

We just put these locked on my enclosed trailer the very next day I could hardly get the lock to open I assume from the cold weather. I don’t know if these locks are good in cold weather because we are having issues already
