Stainless-Steel Cylinder Removal Kit

This two-piece tool set is built from durable stainless steel and includes two clamp shafts, two long bolts and an L-wrench. It is designed for office workers and DIY repairers who need to replace a worn gas lift on a sinking chair without calling a technician. No extra tools are required to complete the job.

28 mm Diameter Compatibility Limit

The clamps fit only cylinders measuring 28 mm or 1.1 inches in diameter, so chairs with thicker or thinner lifts cannot use this kit. The tool works on most standard office, executive, stool and gaming chairs that share this common size. Always verify the cylinder diameter before starting the repair.

600-Pound Load Rating

Once installed, the replacement saver holds up to 600 pounds, making it suitable for heavy-duty daily use. This single figure decides whether the kit matches the weight demands of the intended chair and user. Exceeding this limit risks premature failure of the repair.
