ABSTRACT:
A frame insert for raising the level of a drainage grate cover with respect to a catch basin frame. The frame insert includes a lug for providing a locking surface for a lock device connected to the grate cover. The lug permits a pre-existing lock which locked the grate cover to the catch basin frame to be used to lock the grate cover to the frame insert. The lock engages the frame insert lug at a new lock position which is approximately ninety degrees from the position where it locked the grate cover to the frame before installation of the insert.
