Dolle Prova railings are designed around a slim European aesthetic, not surprising for a company based in Denmark. The modular system can be configured in 18 different combinations with a variety of infill materials, such as tubing and stainless steel cable. Designed for durability, components include aluminum posts and railings (beech wood for interiors), and stainless steel fasteners, fittings, and anchors. Prova railings were recently introduced in the U.S. and are represented by The Dillon Group in Minneapolis. The company promises quick lead times and will help with layout design.
