The present invention is an edge extrusion which is attached on the peripheral rim and to the sidewall of a shell of a plastic container. The edge extrusion has either a male or female joining edge. A rubber gasket is placed between the male and female joining edges in order to seal the plastic container. The present invention also includes casing hardware such as hinges, clamp assemblies and handles, all of which have a base which is adapted to be attached and secured to the edge extrusion without the use of rivets or epoxy. The edge extrusion has a pair of L-shaped flanges, oppositely disposed to each other and parallel to the plane of the sidewall of the container. The base is a rectangular member adapted to loosely slide between the two L-shaped flanges and it has a set of flanges protruding from one of its longitudinal sides. The base has a set of semi-circularly cut holes disposed adjacent to its other longitudinal side and adapted so that a portion of the base between the other longitudinal edge and the semi-circularly cut hole may be deformed in order to secure the base within the L-shaped flanges of the edge extrusion. The edge extrusion is adapted to extend along the entire peripheral rim of the shell and closes on itself. The edge extrusion has a set of ridges disposed on its surface contacting the sidewall of the shell in order to provide additional secureness of the edge extrusion to the sidewall of the shell.
