Chair clamp kit for gas-lift cylinders

This Klein Tools kit contains two stainless-steel clamps and two hex wrenches designed to stop an office chair from sinking. The clamps fit lifting cylinders with an outer diameter of 25 to 27 mm and are secured with the included wrenches. Installation requires no cylinder replacement and can be completed in minutes.

Suitable for standard 25-27 mm cylinders.

The kit suits owners of typical office chairs whose gas-lift columns measure within the 25-27 mm range. It will not work on chairs with thinner or thicker cylinders, nor on models that use a non-cylindrical lift mechanism. Buyers who need a different clamp diameter should look elsewhere.

Clamp fits 25-27 mm cylinder outer diameter

The single specification that decides compatibility is the cylinder outer diameter of 25 to 27 mm. Measure the column before purchase; if it falls outside this range the clamps cannot grip securely and the chair will continue to sink.

Questions about this item

Will these clamps fit the 25-27 mm gas-lift cylinder on my current chair?

Yes, the clamps are designed for cylinders with an outer diameter of 25-27 mm (0.98"-1.06").

How can I confirm the clamps are holding the chair at the right height after installation?

Sit on the chair; it should stay at the set height without sinking and the seat should rotate smoothly.

Does the kit include the hex wrenches needed for installation, or must I buy them separately?

The kit includes two hexagon wrenches (M6 size, 86 x 32 mm) so no separate purchase is required.
