Ruote piroettanti di ricambio per sedie da ufficio, ruote fisse regolabili con feltrini autoadesivi, confezione da 5 (nero/argento)

The standard 7/16 inch x 7/8 inch (11 mm x 22 mm) clamp mounting rods attach to most standard chair or stool bases. Each caster comes with a clamp axle, allowing for tool-free installation onto office chair bases. The total sliding height after installation is 2 inches, similar to most small chair casters. These stool or office chair casters can convert any office chair or desk chair into a fixed seat. They can also convert a caster office chair into a fixed seat without changing the chair's height. Each rail supports 110 lbs, and a set of 5 rails supports 550 lbs. These casters remain stable on smooth surfaces such as wood, tile, and laminate flooring, and offer greater grip than traditional casters. They provide a safer seat for those who have difficulty getting in and out of vehicles.
