Made in Britain, Trusted Worldwide
For more than two decades, Pro Lock has stood at the forefront of valve lockout innovation. What began as a simple idea—creating a universal, colour coded lockout device that any operator could use safely and confidently – has grown into a global standard trusted by industries across the world.

Our founder, Neil Blair invented the first-ever universal colour coded valve lockout device, a product that reshaped safety practices and set a new benchmark on worksites. That spirit of innovation still drives everything we do today. Every Pro-Lock is manufactured in Britain, ensuring exceptional quality and reliability from the moment it leaves our facility.

  • 6,000,000 Pro Locks sold and counting
These figures reflect more than just growth; they represent the trust placed in our products by safety professionals, engineers, and site managers who rely on the Pro Lock every day.
