Abstract: A method of stabilizing a closet ring to a floor by first attaching to the bottom of the floor, with fasteners driven from above the floor, a stabilizing device having a support panel with a length and a width greater than a width of a toilet to be attached to the closet ring. A sewer pipe or extension therefrom is inserted through an opening in the stabilizing device and bonded to the stabilizing device. A closet ring is then fastened to the floor followed by conventional application of a wax ring and a toilet. An elongated anchor tool having wide gap in one edge with teeth-like projections may be used to hold the stabilizing device in place from below for a user to drive fasteners from above into and through the floor and into the stabilizing device.
