A drain and cleanout spacer which facilitates height adjustment of the drain strainer and cleanout port after pouring a concrete slab floor. The device comprises two cup-shaped plastic spacers joined by a flexible web. The first spacer has inside dimensions slightly larger than the outside dimensions of the drain strainer, while the second spacer has inside dimensions slightly larger than the outside dimensions of the cleanout port. The spacers are preferably made from a frangible material, such as plastic. The spacers are placed over the drain strainer and the cleanout port prior to pouring the concrete slab floor. After the concrete has hardened, the tops of the spacers are broken away and the height of the drain strainer and the cleanout port are adjusted to the level of the floor. Thereafter, caulking is applied around the dram strainer and the cleanout port in order to seal them to the floor. A flag is coupled to one of the spacers in order to easily signal the location of the device. This reduces the chance that the device will be inadvertently covered with concrete or stepped on by a worker. Also, a flexible web couples the first and second spacer and provides a downward moment to each spacer which acts to keep the spacers in place when the concrete is poured.
