BD-Q31 Pneumatic Cylinder Lock
BOZZYS pneumatic cylinder locks are compatible with cylinder neck rings and valves with a maximum diameter of ≤80mm. The 3-hole concentric opening and closing structure is compatible with multiple cylinder sizes, effectively preventing cylinder valve misoperation and illegal opening.
- Made of high-quality PP through one-piece injection molding, heat-resistant and insulating, with a wide temperature range of -20℃ to +120℃, suitable for harsh industrial environments.
- Features an anti-misoperation structure design that prevents rotation and displacement after locking.
- A 3-hole concentric opening and closing structure is compatible with various sizes of gas cylinder neck rings ≤80mm, supporting simultaneous locking of 3 safety padlocks for collaborative LOTO management by multiple people/departments.
- Tool-free snap-on installation significantly improves on-site maintenance efficiency.
- Supports customization of various colors and laser logos, and can provide customized locking solutions.
- Comes with a built-in DANGER warning label, which can be used to identify responsible persons, strengthening on-site safety management and doubly preventing misoperation.
- Widely compatible with various gas cylinders (forklift methane tanks, propane storage tanks, etc.), used in conjunction with safety padlocks and warning signs.
