Its aircraft-grade aluminum body and stainless steel shackle deliver exceptional durability and weather resistance. Made in the USA by a veteran-friendly manufacturer, this lock is exclusively compatible with PACLOCK’s PRO-Series LOTO system, offering unmatched security and reliability for professional environments.

## Description

The “90A-PRO” Series of safety lock out (LOTO) padlocks are the best LOTO padlocks in the world. The industry standard for plastic locks was 40,000 key changes however PACLOCK introduced the only LOTO padlock with more than 200,000 guaranteed unique key numbers. “Unique” meaning that not one of those more than 200,000 key numbers will open any of the other padlocks ~ and “guaranteed” means PACLOCK will pay anyone $100 if they ever find a key that opens a padlock that it was not made for. No other manufacturer on the planet can do this or will do this. PACLOCK will and does because that’s how confident we are in our products. The second critical difference on our LOTO padlock is that it is made in the USA with global components! This lock is not compatible with PACLOCK's UCS or Standard Rekeyable padlocks.

Review: High end and super fun to pick - I bought this lock mainly to complete Paclock’s “200k challenge”, where you record yourself picking and gutting the lock and they reward you with a patch and certificate. It arrived today and I’ve since picked it open 3 times. It gives excellent feedback and is super fun to pick. Its actual difficulty level is debatable though. 7 pins and 200k key combinations is useful against certain attacks but a good picker will get it right open, and without getting into minutiae I’ll say there’s a very certain method to getting it open quick, and now I’m halfway tempted to buy another one and test that theory. I wonder how much of Paclock’s sales on this come from people like me anyway. My goal is to keep my picking and gutting video under 5 minutes and that won’t be too difficult. I prepared myself for this with a tricky American Lock 1100 and a German Abus 72/40 and I was well prepared. Now onto real life applications, this is a super heavy duty lock and the 7 pin keyway cannot be picked by anyone without some pretty significant skill and experience with security pins. The weak point on any padlock like this is the shackle and the best part about this is that the shackle is replaceable. Small consolation if it gets cut off and your stuff gets stolen, but at least you probably won’t lose the lock. Finally, these come with stainless steel pins and if you get one with a stainless shackle it just will not rust. And finally it’s a quality American made product and operating it is just satisfying, whether you’re turning it with a key or a tension bar. Guess it’s time to get recording! Got a patch and a blue belt waiting for me.
Review: Nice lock - Well, I bought this for locksport practice and have yet to give it a try. I'm quite sure it would be sufficient to safeguard your goods.

### ⭐⭐⭐⭐⭐ WINNER! hooray to paclock. v tight tolerance seven pin core (6 security), keyed w steep bitting
*by M***S on February 19, 2025*

It's an industry standard for a reason, tight tolerances, seven Pyne total six of which are security pins (alternating spool and serrated and standard in the seventh slot), no spring resistance on the core: picking one open, you have to know what you're doing and be hone in your skills. I'd put it ahead of dozens of locks costing two or three times as much by other companies. Place it comes in a whole bunch of really cool colors so that's super cute and fun. Whether it's customized for your personality or color-coded locking systems, you can go nuts get a whole rainbow of the paclock pro 90 a's.
