ABSTRACT:
A slotted insert having a U-shaped frame and a plastic nut box forms a concrete cone having a depth which is substantially equal to the height of the insert by utilizing tapered feet. The interior sidewalls of the U-shaped frame are formed with indentations or through holes, and the plastic nut box is formed with first projections that are in register with and held by the indentations or through holes. As a result, assembly of the nut box into the frame is accomplished by snapping the nut box into the frame. The nut box, which is also formed with a second projection that fits within the slot of the insert, is formed from a lid that is plastic welded to an open box.
