Rail Systems

Urban & High Risk Areas (IBC-Based)

Rail systems that attach to buildings, such as visitor centers, or that are on trail bridges in urban settings and high-use areas that can reasonably be expected to attract unsupervised, small children, must meet the requirements of the applicable building code. The rail must be at least 42 inches high and not be easy to climb. A 4-inch diameter sphere must not pass through openings from the top of the deck to 34 inches and an 8-inch sphere must not pass through openings from 34 to 42 inches above the top of the deck.
