Dörner + Helmer Apparatus castor

With the apparatus swivel caster, you can easily move lightweight furniture and items without damaging the floor. The caster features a TPE tread and a swivel joint. The thread guard prevents dirt from settling on the axle and blocking the wheel. Casters with soft treads should not be used on unsealed, absorbent surfaces such as stone, wood, or parquet. The white oil that may be present in TPE casters due to production can leak out and cause contact discoloration. On sealed floors, this oil evaporates without leaving residue. At high temperatures, grease from the swivel or bearing may leak out. Please check the floor compatibility before use. On softwood, cork, or similar flooring, all casters may leave indentations or streaks.
