Kleer railing system, KleerRail PVC Railing, offers blind fastenings, making it designed to be assembled rather than nailed together. The cellular PVC is reinforced with aluminum for additional strength and is intended to look and feel like painted wood. Personalization for decks, porches and patios can be done by bending, adding mixed materials or painting the railing system. The systems are available assembled in 36-in. by 8-ft. and 36-in. by 6-ft. sections and well as six feet and eight feet sections to be assembled.
