Telescoping Gas Cylinder Cover

The WORKPRO S1777-1 is a three-piece metal shroud that slides over a standard office chair gas lift cylinder. It shields the piston from grease and stops dust or lint from collecting on the exposed rod. The cover suits home or workplace seating that uses a conventional pneumatic lift mechanism.

Extension Range Limits

The shroud collapses to 4.5 inches and extends to 13 inches, so it only fits cylinders whose stroke stays inside that window. Chairs with taller or shorter gas lifts will leave the piston partly exposed or prevent the cover from seating fully. The telescopic action follows the seat height adjustment without binding.

Three-Piece Construction

The assembly splits into three interlocking sections that snap together around the cylinder without tools. This design allows installation on chairs where the base cannot be removed easily. Buyers needing a one-piece sleeve or a cover for non-standard cylinder diameters should look elsewhere.

Questions about this item

Which length should I choose for my chair — the 4.5 inch collapsed or 13 inch extended size?

The shroud telescopes from 4.5 inches compressed to 13 inches extended, covering most standard office chair gas cylinders through their full travel.

What does the 300 pound capacity mean when the cover is on my chair?

The 300 pound lift and pull rating applies to the gas cylinder itself; the shroud adds no structural load but protects the piston from grease and dust during use.

How does the adhesive compatibility affect installation on a metal cylinder?

The cover fits by sliding over the cylinder without adhesives; the listed adhesive, enamel and epoxy compatibility refers to the metal material's general resistance, not a mounting requirement.
