Abstract
Abstract A safety barrier for railing systems for preventing entrapment, serious injury or death resulting from bodily penetration through the baluster support members of a railing system. The barrier substantially covers the horizontal space between vertical support members and the vertical space equal to the height of the balusters by weaving a mesh scrim or web of poly-vinyl-chloride in primary form plasticized between and along the balusters resulting in taut coverage of the open spacing. A border fabricated of reinforced nylon, canvas or like material is joined to each end of the barrier, having a plurality of openings to allow a means for tightly securing the barrier to an end wall, post or any combination thereof. The barrier is adaptable to lesser dimensions in terms of length and height.
