About this detail

Round spiral ductwork details show acceptable and prohibited tap configurations, including straight saddle taps, straight tees, low loss tees, conical tees, conical saddle taps, and lateral fittings. Reducer transitions, solid welded mitered ninety-degree elbows with turning vanes, and forty-five and ninety-degree elbows with a radius-to-diameter ratio of one point five are detailed alongside spiral supply duct gauge schedules and spiral fitting diameter tables. Saddle type tap fittings are restricted to locations explicitly drawn on plans, and all fittings require a gauge one step heavier than the adjoining duct and no less than twenty-two gauge.
