Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at these TRIMAX two hidden steel padlocks. These high-security, hidden shackle padlocks feature large lock openings to cover and secure all trailer hasps to deter theft. These locks are perfect for trailers, trucks, gates, and sheds. And they are a universal fit, but they are also designed to use with the TRIMAX trailer hasps.
And we do sell those here at etrailer.com. I am including our item number for those hasps. You can just take that item number and insert it into the search field of our website here at etrailer.com. And that item number on your screen will take you to those hasps. Now, these locks are designed and manufactured from one solid piece of steel for long-lasting durability.
They are weather resistant and there are no springs to rust. And as you can see, these are gonna be very easy to use. You just insert the key and give it a turn. And just pull up on the lock and that will unlock the lock for you. These locks are keyed alike and they include six keys.
And just to give you some overall measurements to make sure that this is going to work for your application, looking at the overall height and I am measuring here where this would be considered to be the tallest point here of these locks, we are sitting right at 1 5/8 inches tall. And then the overall width, we are sitting right at, right about 2 7/8 inches wide. And that shackle diameter is 3/8 of an inch. And these do have a limited lifetime warranty. And again, these are going to come in a quantity of two.
But we also, if you're needing just one more, we do carry these in a package of three as well. And on your screen, I am including our item number. If you need more than two and if three would fit the bill for you, the item number there is on your screen for the package of three. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

Nice trailer locks that fit my needs very heavy
Work great!
Worked as designed. Fit on the trailer door closures without a problem.
These locks are great. Easy to lock on my trailer and show now signs of rust after one year of use.
Received Puck Locks sooner than expected and was surprised at weight of package. After checking each lock and making sure each key worked on all locks, locks seemed to be of very good quality. Checked with friend who works in a trailer/shipping yard, he said locks were much better than M***er Locks his company uses. Put locks on trailer doors and they are a very good fit.
As usual etrailer had what I needed and shipped it fast.
purchased to secure our blaylock trailer coupler lock, fit perfectly
They are not “universal”. One fit just fine on my man door. The back latches did not fit and when I tried to fit it upside down (big mistake) it got stuck. Now I’m going to have to cut it off to get my trailer door open. The one photo with no lock is the same as the other side. It doesn’t fit either. No surprise there.
Just what i needed.
Wow! What a great set of locks! Fits over the shackles and completely secures the tailgate! Would take a great effort to circumvent!
Very fast delivery and product was exactly what I ordered. Thanks
The lock may be great, I’ll only know if I discover it deterred a theft. My 3 stars are about the recognition that my order took weeks longer than originally informed. A couple days after it was due, I received a message saying that the order was delayed because of product unavailability. It was already overdue, I wish I’d been updated earlier, so I could possibly find another option.
This company is great in some ways. When I ordered my first order (a trailer hitch assembly kit to be installed on my vehicle.) I received same day response from the CSR team. A month or two later when I tried, more than twice to get some answers, I never received a single call or reply.
I instead sought help from a local vendor.
But because the actual product was not the issue, I returned my business for additional purchases.
Average is all I have to report about this company. At least average is better than lousy.
The locks are of good quality. Shipment was fast. Will order from you again. Also good communication on shipping information. Thanks
I've had typical padlocks maliciously cut off my trailer door previously, so I was looking for something to prevent this. These locks easily fit on the hasps on my trailer. They are essentially impossible to cut short of using some kind of heavy-duty power tool. They are attractive and appear to be weather resistant. They have lubrication ports. I'm very happy with my purchase of these locks.

After a year Im still quite satisfied with these locks. Keeping them oiled keeps them working easily. They are still attractive and my trailer is secure.

These have been in use for a year and still open and close smoothly. Don't beat up the back of my cargo trailer and very secure. Really like that they come with 3 keys.
They were a bit tight on my hasps at first, but they work fine now. Keyed alike too, which is nice.
They fit fine, work fine. They a
improved security to a degree. Just making it a little more difficult to get in.

I have these locks on a 7 x 10 enclosed trailer. I have the trailer parked under a carport. These locks are suppose to be stainless steel, which i thought wouldnt rust, but the locks are rusting. if i order more i will order aluminum.
