The NW 125 slotted channel was developed for the increasing number of arenas with level playing fields.

Open channels without upstands are used, as the running track and segments are generally at the same height. In the ANRIN SPORT drainage system NW 125, the polymer concrete channel body and a HDPE plastic cover form a sensible combination of drainage and running-track bordering. The covers comply with DIN 18035 and international athletics regulations.
