Protection against slipping through for downwardly open stairs steps

摘要

There are locating components (3) on the two outer ends of the clamp tubes (2). Each locating component is adjustable as to height by a threaded rod (5). Slipping out of the adjustment tube (1) is prevented by a safety clamp. The adjustment tube is shortened to correspond with the individually required width of the stairs. The adjustment tube is produced with a through-hole series, which is used to secure by a spring pin the adjustment tube against slipping out or being withdrawn from the clamp tubes. All the tubes are produced from various hard materials and are assembled from different profile bodies.
