Abstract: A cover grating for manure removal canals in stables is formed of elongated lower supports disposed in lateral spaced relation with elongated upper supports mounted on and extending transversely of the lower supports. The upper supports can be inserted downwardly into the lower supports in a direction extending transversely of the longitudinal directions of the upper and lower supports. Openings are formed in the lower supports extending transversely of their elongated direction. The upper supports have downwardly projecting longitudinally extending flanges supported on the lower supports. Further, downwardly extending pawl strips in the upper supports extend through the openings in the lower support and are lockably engaged with walls within the lower support. The walls within the lower support divide it into individual box-like chambers.
