Without scratches and noise when rolling: The high-quality office chair castors from one concept set a new standard. Go quietly through the office from the desk to the filing cabinet with minimal effort. Gone are the days when office swivel chairs with casters made of hard plastic leave unsightly marks on your expensive floor. The black parquet castors made of soft polypropylene are suitable for use on all floors - whether laminate, parquet, tiles, PVC, vinyl, bamboo, carpet or polished concrete - no scratches or signs of wear are left behind. The use of a floor protection mat is therefore superfluous. Due to the large chair castors, the high-quality premium ABEC-7 ball bearings and the sturdy metal suspension, even carpets do not reduce the rolling comfort. Assembled together, all 5 castors can withstand a total load of 250kg. The castor set includes 5 wheels that you can attach to all desk chairs in no time at all with a standard 11mm hole and a 22mm pin. Simply pull off the old castors and insert the premium hard floor castors from one concept with the pin into the thread.
