The main material is black nylon, with a specified structure that also refers to PU and metal components. The base diameter is 50 mm, the contact specification is 11 x 22 mm, and the installation height is 22 mm. The package includes 5 replacement glides for a swivel chair.

Core features:
These replacement glides are intended to convert a rolling swivel chair into a fixed office chair without losing the chair's height.

Suitable for most standard office chair caster fittings, these glides can be used on office chairs, workshop chairs, and other stools where fixed support is preferred. They are described for use in home offices and corporate offices, especially in environments with carpeted floors, polished concrete, vinyl floors, tiled floors, rugs, and other permanent floor surfaces. The description also notes floor protection considerations for wood, laminate, and other softer floors.
