Sheerline® is the #1 vinyl rail system, offering the most wood-like appearance of any vinyl rail system on the market. Sheerline® top rails have added detail, replicating cove molding, a design technique utilized by master woodcrafters. Our rails are larger and have greater depth than most competitive rails, adding style and strength to Sheerline’s railing system. The unique, distinctive appearance and dimensions of our pickets compliment and balance the prominent scale of our railing.
