    Product features

    1. Higher manufacturing precision of working platform: The manufacturing precision of working platform is high, facilitating installation and is of precise orientation. The working platform has a through hole in the center, and pipes can be located and passed through the hole.
    2. Double cylinder structure brings about double output.
    3. Two modes of buffer are offered for selection, including adjustment bolt buffer and internal shock absorber with the latter even better.
    4. Rack and pinion design makes for stable functioning.
    5. The device comes with integral magnetic switch slots
    6. Three types of size are selectable which are mini-sized (2, 3 & 7), middle-sized (10, 20, 30 & 50) and large-sized (70, 100 & 200) rotary cylinders.
    7. Simple installation: Guide holes are designed on both sides of the cylinder body (10~200) or undersurface (2~7).
