ABSTRACT:
A slotted drain includes a drain pipe having an elongated narrow slot extending lengthwise along its top surface. A lower grate is rigidly secured to the elongated slot and is formed by a pair of bearing plates connected to one another by a series of spacer plates and connected to the edges of the elongated slot. The lower grate is connected to an upper grate initially in an adjustable manner such that the height and angle of the upper grate may be adjusted with respect to the lower grate and the drain pipe. The height of the upper grate with respect to the drain pipe is dependent upon the intended depth at which the drain pipe will be situated and the angle of the upper grate may, for example, correspond to the drainage slope at which the drain pipe will be set. Once the upper grate has been adjusted to the desired height and angle, the upper grate is rigidly secured to the lower grate. In a first preferred embodiment the lower grate telescopically receives the upper grate and in a second preferred embodiment the upper and lower grates are connected to each other by a pair of intermediate bearing plates.
