Crandall Office Furniture’s Steelcacse Turnstone TS311 Uno aftermarket stool gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
A office chair gas cylinder is the height adjustment mechanism on the chair. The typical life span of a office chair gas cylinder is 4-7 years, depending on use and abuse. If failed, your chair will be left with limited or no height adjustment, however you can quickly and easily replace your broken Steelcacse Turnstone TS311 Uno stool gas cylinder today.
Our Steelcacse Turnstone TS311 Uno gas cylinders are made to fit all Steelcacse Turnstone TS311 Uno chairs.
This cylinder can successfully be used on a standard Steelcacse Turnstone TS311 Uno chair, to convert it to stool height, standing desk, sit-to-stand desk, or bar height. Also available is our full stool conversion kit (including foot ring) for the Steelcacse Turnstone TS311 Uno chair.
If looking for a standard stool height, please consider the 8″ stool cylinder, the 10″ cylinder provides a significant increase in sitting height of the chair, and should only be considered if the 8″ stool cylinder does not reach high enough.
- Overall Length / Maximum Extension: 28.25″
- Overall Length / Minimum Extension: 18.50″
- Amount of adjustment: 9.75″
We have included installation instructions to help you install your aftermarket replacement stool gas cylinder (same procedure as a standard gas cylinder), but please feel free to contact us with any issues or questions.
