U.S. Made with Global Components

We engineer, CNC machine, assemble, and quality test nearly our entire product line in the USA.

Precision CNC Machining

We use American-made Haas CNC machines to produce
high-quality locks with tight tolerances.

U.S. Family Business

We are the only independently owned and operated padlock manufacturer in the world producing aluminum, brass, and hardened steel padlocks.

Short Lead Times

Because we manufacture in the USA, most orders ship within 2-5 business days - the competition takes months to deliver.


Our dedication to engineering innovation means quickly developing custom solutions and continual improvement to existing designs.

What Our Customers Have To Say

"PACLOCK's craftsmanship on these locks is top notch, and their commitment to their customers is unwavering. I bought a pair at one time, and they came keyed alike. They shipped and arrived quickly, and I will absolutely buy more as the need arises."
Jonathan M. Towne
"Nice Padlock!!! Well worth the price. Will be replacing all of my old "Master Locks" with these."
"The second lock I have purchased from Paclock. The first one I bought directly from them before I knew they sold on Amazon. I asked if I could get the second lock keyed the same as my first and they happily accommodated. The locks look and feel like a far better quality than the typical locks you find. Also while they don't currently offer prime shipping I still received my lock in two days."
