Take-out of an elbow cut to an angle

Elbow radius (centerline)

Examples: 12', 5' 3 1/2", 3/4", 2.5m

Angle after cutting (°)

Take-outs depend on fitting size, schedule and maker: measure the fitting or use the maker’s dimensions. For threaded fittings use center-to-face minus thread engagement. The elbow helper uses radius × tan(angle ÷ 2). Estimates only. Check measurements, product labels and local building codes before you buy or build.
