An in-ground apparatus includes a receptacle and a liner into which the receptacle can be placed and removed. The liner may be a molded plastic liner having a tapering body to permit stacking. The lower margin includes a set of seats for anchor fittings in the form of re-bar prongs that, when installed, extend radially outwardly from the liner. The seats, and hence the prongs, are located upwardly of the bottom edge of the liner so that they are embedded above and below when concrete is poured around the bottom of the liner. The bottom edge of the liner is folded upwardly and inwardly to form a V-shaped channel. The seats for the anchor fittings extend across the channel. The seats may include a cylindrical wall sealed from the inside of the liner. The liner may have intermediate stiffening ribs between bottom and top. The top of the liner may have a seat for the receptacle, and an external concrete break.
