Used to prevent access to the main cylinder valve, the unit encloses the valve head and is locked in place with two interlocking plates. Installs in seconds and provides quick and easy identification of a full cylinder, with the security of a padlock to lock the device in place to prevent unauthorised use. Each lockout is supplied with two extra labels, your choice of which can be fixed onto the lockout to depict if the cylinder currently being locked out, is full or empty.
