- a top panel having a perimeter, said perimeter having at least a first edge, a second edge, a third edge and a fourth edge, said top panel having a topside and an underside disposed between the first, second, third and fourth edges; and
- a first side wall extending in an integral fashion from the underside along the first edge, the first side all having at least one slot through which accessories of the ladder can be attached, an opposing second side wall extending in an integral fashion from the underside along the second edge, a third side wall extending in an integral fashion from the underside along the third edge an din juxtaposition with the first and second side walls, and a fourth side wall opposing said third side wall and extending in an integral fashion from the underside along the fourth edge an din juxtaposition with the first and second side walls, said at least one set of legs attached to the ladder top through the third and fourth side walls.
- 2. A ladder system as described in claim 1 wherein the third and fourth side walls having holes through which the at least one set of legs is attached to the ladder top.
- 3. A ladder system as described in claim 2 wherein the first side wall has two slots.
- 4. A ladder system as described in claim 3 wherein said slots are disposed in a spaced relationship with each other.
- 5. A ladder system as described in claim 4 wherein said slots are rectangularly shaped with rounded ends.
- 6. A ladder system as described in claim 5 wherein said top panel has a topside with a grid of ridges integrally formed on said topside of said top panel and extending outwardly therefrom.
- 7. A ladder system as described in claim 6 wherein the top panel includes a plurality of holes arranged in a spaced relationship.
- 8. A ladder system as described in claim 7 wherein the topside of the top panel includes a recess having a circular shaped periphery and a flat base.
- 9. A ladder system as described in claim 8 wherein the second side wall includes a hook extending therefrom.
- 10. A ladder system as described in claim 9 wherein said top panel has an underside and buttressing integrally joined and extending from said underside and connected to said first and second walls for strengthening the top panel.
- 11. A ladder system as described in claim 10 wherein said buttressing has a first leg and a second leg forming a first pair of legs, and a third leg and a fourth leg forming a second pair of legs which extend from said first and second side walls, respectively, and intersect to form an X shape, a portion of said first leg and a portion of said second leg have a first height as measured from the underside of the top panel such that the portion of the first leg and the second leg having the first height extends form said first side wall past the respective slot after which point the first and second legs have a second height, which is greater than said first height, along the remainder of their length, said first height less than a height, as measured from the underside of the top panel, of a portion of a slot closest to the underside of the top panel.
- 12. A ladder system as described in claim 11 wherein said buttressing includes a curved arch which integrally extends from said underside and which extends between the first and second legs and connects thereto at the respective point where the second height of the respective leg begins.
- 13. A ladder system as described in claim 12 wherein the recess is disposed essentially in the center of the topside of the top panel.
- 14. A ladder system as described in claim 13 wherein the third side wall is integrally connected to the first and second side walls and the fourth side wall is integrally connected to the first and second side walls.
- 15. A ladder system as described in claim 14 wherein the top panel, hook, buttressing, first, second, third and fourth side walls are one continuous piece.
