Abstract
Abstract Rigid PVC or other weatherable capstock and a rigid thermoplastic substrate are coextruded to form a channel-shaped cover adapted for close fitting resilient engagement with a plank or beam. If the plank or beam is wooden, the rear marginal flange of the cover may be flared outwardly or inwardly, depending upon the proximity of the planks or beams to one another, and horizontally elongated fastener-receiving slots are provided in at least one leg of the cover. If the beam or plank is formed from metal, the rear marginal flange is inturned to provide a snap fit between the cover and the beam. End caps and connectors are provided to hold the cover in place on the metal beam.
