Replacement 11" black gas lift for draughtsman chairs or for extra height on an office chair.

Suitable for up to 160kg weight limit. The gas lift is approx 375mm - Extends to 780mm.

If you are replacing a failed gas lift, you will need to hit the existing gas lift out of the base with a rubber mallet - they can be stubborn.   The replacement will drop straight into the base and will edge in place when weight is applied to the chair.
