This listing is for a brand new, never-used CLASS 4 office chair seat height adjustment pneumatic gas lift cylinder. The cylinder has a 4.5-inch stroke, allowing seat travel from the lowest to the highest settings. It exceeds the ANSI/BIFMA5.1-2011 standards, and its load capacity is 350 pounds based on the specifications.

When fully extended, the cylinder measures 16 inches, and when compressed, it measures 11.5 inches, with a travel distance of 4.5 inches. The cylinder diameter is 28mm (1.1 inches), and the column diameter is approximately 50mm (2 inches).

If the chair cannot lift normally after installation, the two screws located near where the cable attaches need to be adjusted, as shown in photo 2.

This cylinder is specifically designed for Aeron chairs made between 1996 and 2012, in sizes A, B, and C. It comes with a 5-year replacement warranty.

The package includes only the gas cylinder; the chair itself is not included.
