Abstract
A roof drain cover characterized by an open-end cage adapted to sit over the top of a roof drain. The cage has a top face and a peripheral wall. The top face and the peripheral wall are provided with apertures for allowing water circulation therethrough. A pair of leg members which are suspended from the top wall, have a portion extending below the cage for penetrating into the drain. A pair of bolts are slidingly mounted through the peripheral wall and are coaxially mounted in opposite direction, each of said bolts being threadedly engaged with a corresponding leg member for pulling apart the leg members in the direction of the peripheral wall. When the cage is mounted over the drain, the portions extending below the cage are accordingly adapted to abut against the inner surface of the drain for frictionally retaining the cage to the drain.
