A one-piece, plastic anchor with a cylindrical body and four legs. The hole through the center of the body has ribs on the outside to hold the anchor in place during installation.
When a tapping screw is driven into the toggle, the legs collapse which forms a tongue. As the screw is driven through the body, it pulls in and expands the legs. Plastic toggle anchors are intended for lightweight duty in hollow walls (wallboard or plaster), ie. drapery rods, junction boxes, soap dishes, towel bars, etc.. The anchor remains in place even after the screw is removed.
