Abstract
Abstract An access floor panel includes a generally rectangular pan having a bottom and sides. The pan includes peripheral flanges which define downwardly opening channels or grooves extending around the edge or periphery of the panel. A plurality of elongated, vinyl trim pieces are slidably positioned on the peripheral flanges and disposed within the downwardly opening channels. Each of the trim pieces includes a generally L-shaped slot dimensioned to receive the peripheral flange.
