Abstract: Waste pipe support apparatus comprises two nested, trough type, semi-cylindrical tubular members which are telescopically slideable relative to each other for providing the apparatus with required extensibility and contractibility. A bail-type support leg structure elevates one end of the apparatus relative to the other end and the local terrain. Bracket stops limit the pivotable movement of the support leg structure in its operative mode so as to provide stability therefor, and a nut-and-bolt/slot mechanism is provided within the trough members for providing infinite telescopic adjustment capabilities to the apparatus in the longitudinal direction. Guide means is also defined between the trough members for facilitating the movement and retention of one member relative to the other member during the aforenoted longitudinal adjustment operation. The bracket structure of the apparatus also provides for elevational adjustment of the bail leg structure.
