Our cylinder valve locking devices eliminate the need for multiple locking devices by providing a universal fit. No matter what size or type of cylinder valve you have, our locking devices will fit perfectly without any hassle. One of the main features of our locking device is its neck ring, which locks securely with a maximum diameter of 35 mm. This ensures that the locking mechanism remains in place, providing a solid barrier against unauthorized access. The inner diameter of the locking device is also large, accommodating cylinders with a maximum inner diameter of 94 mm.
