Cellar or rainwater drain system gulley - has telescopically sliding connection for simple compensation of levels

摘要

The cellar or rainwater drainage gulley has a collector. The drain is adjusted with a connector piece to the given level differences between the drainage channel system and the upper ground level. The level differences are readily compensated without use of excessive number of different components. This simplifies the stockholding and overall costs of installation. The upper mounting piece (16) is able to slide telescopically in a sliding seal (24) held in the intermediate connector piece (15). The mounting piece (16) has in its lower part groove (25) parallel to its edge for accommodating an elastic sealing ring (24).
