An apparatus, in combination with at least one of a top shelf and a tray of a ladder, for preventing tipping of the bucket and paint can. The apparatus comprises an opening having a predetermined diameter disposed in at least one of the top shelf and the tray of the ladder. The opening has a first plurality of gear like members disposed on an inner circumference of the opening. There is a disc like member engageable with the opening and having each of a predetermined diameter, a predetermined thickness and a predetermined height. The disc like member has a second plurality of gear like members formed in an outer surface of the disc like member. The second plurality of gear like members for engagement with the first plurality of gear like members on the opening. The present invention also includes a means for attaching the disc like member to a bottom surface of one of the bucket and the paint can.
