ABSTRACT:
A device for stabilizing footing drainage conduits while forming the footings including an annular disk and a cylindrical hub extending outwardly from and about the opening. A drain tile or conduit is engaged with the device about the hub while the device is secured to the footing form. The annular disk extends normal to the cylindrical hub. The device is adjusted to abut the form for the building footings. Accordingly, the devices are positioned and attached to the forms. The device provides support and prevents crushing of an end of the conduit when concrete is poured between the form boards when the footings are created. A nub on the cylindrical hub prevents lateral movement of the device when the footing forms are removed. An adjustable drainage tile can also be used. Two sections of conduit are employed for the adjustable drainage tile. One end of one of the sections of conduit has axially extending slits to allow interengagement of the end of the one section of conduit into the second conduit. The opposing devices can be moved laterally by adjusting the sections of conduit.
