Universal fit for premium task chairs.
The 7/16 inch ( 11.1 mm) friction grip stem with 1 inch sleeve length is the industry-standard mount used by most premium ergonomic task chairs, high-end mesh chairs, designer executive chairs, and contract-grade office seating.
Pull one of your existing casters and verify the stem matches before ordering.
Tool-free installation in seconds.
No adapter, no hardware, no guesswork.
Safe on hardwood, tile, and carpet.
Non-marking medium-durometer polyurethane tires roll cleanly on hardwood, vinyl, tile, laminate, and low-pile carpet without scratching, gouging, or leaving streaks.
One tire compound handles every surface in your home or office, so you can move from rug to wood floor without swapping wheels or buying floor mats.
Whisper-quiet precision roll.
Twin-wheel design paired with two sealed ABEC chrome steel precision ball bearings per caster provides the silent, glassy-smooth roll a premium chair deserves.
No clatter on hardwood.
No sticking.
No flat spots after sitting overnight.
The stock plastic casters that came with your chair don't do this.
