|Boltless shelving is designed to maximize storage space and minimize installation / set-up time. All components are engineered to attach snugly to one another without the use of loose fasteners. This unique design has rivets which are factory attached to all left-to-right and front-to-back beams. The rivets align with keyhole slots in the vertical posts. Once tapped into place using a standard rubber mallet, the units are tightly assembled providing maximum strength.
