A roll-out waste bin includes a retention bar that is held in place on the bin by a pair of retention bar housings. A rib in one of the retention bar housings engages one end of the retention bar and a protrusion on the other end of the retention bar and exterior to both of the retention bars housings positions the retention bar. In another embodiment, protrusions on both ends of the retention bar allow elimination of the rib. In yet another embodiment, multiple protrusions on one end of the retention bar allow positioning of the retention bar.

1. A roll-out waste bin of the type characterized by having a receptacle mounted on wheels, a hinged lid enclosing an open top of the receptacle, a handle, a downward lip along a front top rim of the receptacle and a vertically spaced retention bar for being grasped by an external lifter for elevating and emptying the contents from the receptacle, and including: (a) first and second laterally spaced-apart vertical walls extending outwardly and forwardly from a forward side of the receptacle, and positioned to form respective first and second retention bar housings;(b) a first aperture formed in the first vertical wall and a second aperture formed in the second vertical wall for receiving the retention bar, the first and second apertures having diameters sufficiently large to permit rotation of the retention bar in the first and second apertures;(c) a rib positioned in the first retention bar housing and adapted to abut a first end of the retention bar extending into the first retention bar housing to prevent movement of the retention bar into the first retention bar housing beyond a predetermined point; and(d) an axially-extending, radially-deformable protrusion carried on a second end of the retention bar and adapted to reside in and engage a wall of the second retention bar housing to deform against the wall such that the first end of the retention bar clears the first vertical wall and can be moved into alignment with the first aperture to extend into the first retention bar housing, and to restrain side-to-side movement of the retention bar out of the first and second apertures. 2. The roll-out waste bin according to claim 1, wherein the rib comprises an integrally-formed elongate member that is adapted to engage an end face of the retention bar. 3. The roll-out waste bin according to claim 1, wherein the retention bar is cylindrical and the first aperture and the second aperture are circular. 4. The roll-out waste bin according to claim 1, wherein the first and second retention bar housings each comprise one vertical wall, one front closeout wall and two external walls of the waste bin receptacle. 5. The roll-out waste bin according to claim 1, wherein the axially-extending, radially-deformable protrusion is positioned on an end face of the retention bar to prevent passage of the retention bar further through the second aperture into the second retention bar housing. 6. The roll-out waste bin according to claim 1, wherein the radially-deformable protrusion comprises a flange extending axially from the second end of the retention bar. 7. The roll-out waste bin according to claim 1, wherein the axially-extending, radially-deformable protrusion comprises a plurality of spaced-apart radially-deformable flanges having a width that is a major portion of the diameter of the retention bar and a thickness that is a minor portion of the diameter of the retention bar. 8. A roll-out waste bin of the type characterized by having a receptacle mounted on wheels, a hinged lid enclosing an open top of the receptacle, a handle, a downward lip along a front top rim of the receptacle and a vertically spaced retention bar for being grasped by an external lifter for elevating and emptying the contents from the receptacle, and including: (a) first and second laterally spaced-apart vertical walls extending outwardly and forwardly from a forward side of the receptacle, and positioned to form respective first and second retention bar housings;(b) a first aperture formed in the first vertical wall and a second aperture formed in the second vertical wall for receiving the retention bar, the first and second apertures having diameters sufficiently large to permit rotation of the retention bar in the first and second apertures;(c) a first deformable protrusion carried on a first end of the retention bar and adapted to reside in and engage a wall of the first retention bar housing;(d) a second axially-extending, radially-deformable protrusion carried on a second end of the retention bar and adapted to reside in and engage a wall of the second retention bar housing to deform against the wall such that the first end of the retention bar clears the first vertical wall and can be moved into alignment with the first aperture to extend into the first retention bar housing, and cooperating with the first deformable protrusion to restrain side-to-side movement of the retention bar out of the first and second apertures. 9. The roll-out waste bin according to claim 8, wherein the first deformable protrusion and the second axially-extending, radially-deformable protrusion comprise first and second deformable flanges extending axially from respective first and second ends of the retention bar. 10. The roll-out waste bin according to claim 8, wherein the first deformable protrusion and the second axially-extending, radially-deformable protrusion each comprise a deformable flange having a width that is a major portion of the diameter of the retention bar and a thickness that is a minor portion of diameter of the retention bar, and which extend axially from respective first and second ends of the retention bar. 11. The roll-out waste bin according to claim 8, wherein the combined length of the retention bar, the first second axially-extending, radially- deformable protrusion and the second axially-extending, radially-deformable protrusion is longer than the distance between the first and second vertical walls and shorter than the distance between opposed external walls of the waste bin receptacle. 12. A method of installing a retention bar onto a roll-out waste bin of the type characterized by having a receptacle mounted on wheels, a hinged lid enclosing an open top of the receptacle, a handle, a downward lip along a front top rim of the receptacle wherein the retention bar is spaced vertically from the lip for being grasped by an external lifter for elevating and emptying the contents from the receptacle, comprising the steps of: (a) providing first and second laterally spaced-apart vertical walls extending outwardly and forwardly from a forward side of the receptacle, and positioned to form respective first and second retention bar housings;(b) providing a first aperture formed in the first vertical wall and a second aperture formed in the second vertical wall for receiving the retention bar, the first and second apertures having respective diameters sufficiently large to permit rotation of the retention bar in the first and second apertures;(c) providing a axially-extending, radially-deformable protrusion carried on one end of the retention bar;(d) inserting the retention bar into and through the second aperture into the second retention bar housing to a point where the axially-extending, radially-deformable protrusion on the end of retention bar radially deforms and allows the retention bar to be moved into alignment with the first and second apertures; and(e) moving the retention bar axially out of the second retention bar housing a sufficient distance to cause the radially-deformed protrusion to return to the axially-extending, non-radially-deformed position. 13. The method according to claim 12, and including the steps of providing a rib projecting from an external wall of the first retention bar housing, and extending the retention bar into the first aperture and into the first retention bar housing to abut the rib; and providing a second axially-extending, radially-deformable protrusion on a second end of the retention bar positioned in the second retention bar housing in a radially-undeformed position to restrain side-to-side movement of the retention bar out of the first and second apertures. 14. The method according to claim 13, wherein the first axially-extending, radially-deformable protrusion and the second axially-extending, radially-deformable protrusion each comprise a deformable flange having a width that is a major portion of the diameter of the retention bar and a thickness that is a minor portion of diameter of the retention bar.
