ROOF-CEPTORS® are indirect waste receptors designed specifically for roofs. These units are recommended for use in roof areas to receive waste water from air conditioning units, cooling towers and other mechanical equipment installed on the roof. The 2 1/2" high solid water dam prevents normal rain water from entering the waste line. The large vandal proof dome bottom strainer provides ample drainage and prevents entry of debris. All accessories necessary to install roof drains are available with these receptors.

Designates a wide flange that can be added to certain Smith roof drains. This flange receives and serves as a bonding base for the membranes and coatings of waterproof roof deck covering systems. These coverings consist of thin elastomeric coatings which are applied in a series of trowel coats. The covering forms its own membrane, flashing and durable traffic surface. The DX flange is regularly furnished 4" in width. The usual covering is approximately 3/16" thick and may be applied over many sub surfaces such as concrete, gypsum or wood decks. Such coverings are particularly adaptable to flat roofs, used for recreational purposes, balconies, area ways, plazas, sun decks, floors and corridors.

When the DX flange is required on drains other than those shown in this section, the prefix DX must be used with the figure number. The regular flange will have a minimum 4" width with a 3/16" lip at drain body. If waterproof deck covering thickness is greater (or less) than 3/16”, lip dimension must be specified. Roughing dimensions of the body must be adjusted accordingly. Drain body should be set low enough to permit "dimpling" of area surrounding drain.
