This 50x230 mm gas lift (DKU) with a chrome-plated outer sleeve is made by the Ukrainian manufacturer AMF for operator chairs. The standard 50 mm base size fits roughly 90% of operator chair models on the market.
The mechanism adjusts seat height to the user's needs, absorbs shock when sitting down, and is protected against moisture and dust. The chrome-plated sleeve gives the part a neat look on chairs with an open base.
