Product Overview
ALTRA brings a professional-grade mobility solution to your workspace with the 3‑inch roller‑blade style casters. Engineered with industrial‑grade bearings and a robust steel bracket, each wheel delivers ultra‑smooth rolling across carpet, hardwood, tile, and laminate without leaving any marks. The set includes five wheels, each measuring 3 × 1 × 4 inches and weighing just 2.5 lb, yet collectively they support up to 650 lb of total load. Designed for universal compatibility, the casters fit 99 % of office chairs that use a standard 7/16″ stem diameter and 7/8″ stem length, making them a hassle‑free upgrade for most seating solutions. The non‑marking polyurethane tread protects delicate flooring while the precision‑machined bearings reduce friction, ensuring a whisper‑quiet glide that enhances productivity and comfort.
