Create custom performance set-ups with National Public Seating’s Tapered Standing Choral Risers with Hardboard Deck. The durable solid plywood decks taper forward, and form smooth turns when combined with other straight or tapered risers. Built-in ganging braces let you safely and easily combine multiple units. A 16-gauge steel frame with 14-gauge legs provides sturdy support, and spring-loaded leg brackets make your risers a cinch to set up and fold for storage. This model features tempered hardwood laminate deck surfaces.
