Abstract
A combination of a cover plate and a drain, preferably a floor drain is described. The cover plate is provided with first locking means and the drain is provided with cooperating second locking means for releasable connection of the cover plate to the floor drain. The cover plate is a temporary cover plate for use during installation of the drain. The cover plate may be used for a temporary protection of a drain during installation of the drain and for installing and adjusting the inclination of the drain without the need of separate levelling tools. To obtain this the cover plate is provided with levelling means for determining the orientation of the cover plate and thereby also the drain in relation to a horizontal or a vertical plane. The first locking means or the second locking means comprises a weakening arranged such that at least a part of the locking means is preferably damaged when the cover plate is removed from the drain to ensure that the cover is not reused.
