Master Lock is the classic American “padlock brand” - the one that’s been on job sites, school lockers, garage doors, and storage units for so long it’s basically part of the urban landscape. The company was founded in 1921 by locksmith-inventor Harry Soref in the Milwaukee area, built around his breakthrough laminated steel padlock design: strong, affordable, and mass-producible — the security industry’s equivalent of discovering fire, but with more rivets.

What they’re known for is broad “portable security” rather than door hardware:

Padlocks (keyed, combination, weather-resistant, heavy-duty)
Lock boxes / key safes (mechanical and Bluetooth variants for managed access)
Safes and security storage (varies by market, often alongside their lockbox line)
Lockout/Tagout (LOTO) safety products for industrial settings (a big part of their professional footprint)

Ownership / group: Master Lock is a subsidiary within Fortune Brands Innovations’ security portfolio (the same broader group that also houses other security brands).

Our range of Master Lock security solutions includes a comprehensive selection of padlocks, key safes, and hardware designed for domestic, commercial, and industrial use.

For physical security, we stock heavy-duty ProSeries laminated steel padlocks, weather-resistant Excell discus locks, and robust open-shackle models. If you prefer keyless convenience, our combination lock range covers everything from everyday locker locks to TSA-approved travel luggage locks. We also supply specialist Zenex thermoplastic safety padlocks for industrial Lockout Tagout (LOTO) requirements.

To secure gates, sheds, and commercial doors, we offer high-security steel hasps and staples, including heavy-duty American Lock options. Additionally, our selection of wall-mounted Select Access key safes provides a secure way to share keys with family, guests, or carers, featuring options with illuminated dials and high-security ratings.
