A CO2 carrying handle, especially for small cylinders like 2, 3, or 4.5 kg, typically features the following characteristics:

1. Material: Made of mild steel for durability and strength. Mild steel is a common choice for such applications due to its affordability and suitability for fabrication.

2. Design: The handle is designed to securely grip the neck of the CO2 cylinder, providing a stable and safe way to carry it.

3. Ergonomics: The handle design prioritizes ergonomics, ensuring comfortable handling even when the cylinder is full. This may include rounded edges and a comfortable grip.

4. Weight-bearing capacity: Designed to withstand the weight of the filled CO2 cylinder without bending or breaking. The design should distribute the weight evenly to prevent strain on the handler.

5. Attachment mechanism: Depending on the specific design, the handle may feature hooks or clips to securely attach to the neck of the CO2 cylinder.

6. Coating or finish: To prevent corrosion and enhance durability, the handle may be coated with paint or another protective finish.

7. Compatibility: The handle should be compatible with various sizes of CO2 cylinders, such as 2, 3, or 4.5 kg, ensuring versatility and usability across different applications.

8. Safety features: It may include additional safety features such as anti-slip padding or locking mechanisms to prevent accidental release while carrying.

9. Portability: The handle should be lightweight and easy to transport, adding minimal bulk to the overall weight of the cylinder.

10. Cost-effectiveness: While providing all necessary features, the handle should also be cost-effective to manufacture and purchase, making it a practical solution for handling CO2 cylinders.
