Pro-Lock® Valve Lockout Devices


The Pro-Lock® valve lockout device was designed to replace any known valve lockout system and can work stand-alone, support additional security or fit seamlessly into existing permit-to-work systems.

By securing with the Pro-Lock® Operating Tool, no additional security is required.

Pro-Lock® devices are moulded from high quality, UV stabilized, polypropylene. The internal components are all stainless steel and DERA Testing has verified Pro-Lock® as suitable for use from -55°C to +55°C.

Pro-Lock® valve lockout devices are available in Red, Green, Blue and Yellow for easy identification of the employees using the devices, the contents of the pipework being isolated, or whether the valve is locked/open/closed/part of a wider isolation.

Our devices are also designed to be reusable, thus cutting down on wastage associated with traditional lockout devices.
