The “90A-PRO” Series safety lockout (LOTO) padlocks are the best LOTO padlocks in the world. While the industry standard for plastic-body LOTO padlocks is approximately 40,000 key changes, PACLOCK delivers the first LOTO padlock backed by more than 200,000 guaranteed unique key numbers. PACLOCK backs its “No Key Interchange” guarantee by replacing the lock and paying $150 to anyone who finds a key that opens the wrong lock. While at least one competitor now claims 200,000+ key changes as well, PACLOCK recognized a simple reality: most customers would never discover key interchange problems on their own. That’s why PACLOCK put money behind the guarantee. Because there’s a difference between claiming key changes and guaranteeing them. Why did PACLOCK enter the already crowded LOTO industry? Check out PAC-PREZ’s fireside chat on YouTube. The 90A-PRO is also proudly made in the USA with global components — another critical difference in a category dominated by imported alternatives.
