  • Publication number: 20040094496
    Abstract: An integral pallet rack post reinforcement kit for protecting the lower pallet rack frame from forklifts, etc. which takes the place of the lower six to twelve inches of the front frame post and fastened in its place. The kit is, for example, square tube welded to a three-sided outer clamp which bears a front angle deflector. These components are welded to a four inch by twelve inch by three-eighths inch footplate with two three-quarter inch by five inch by half inch wedge bolt anchors for attachment to the warehouse floor. Accordingly, this footplate replaces the original footplate. By using the reinforcement kit with the angle deflector, frontal impacts are deflected off to one side. The front post of the original pallet rack the present reinforcement kit would, over time, fail from cyclical or repeated impacts.
