Elbow flanges (Figure 21)
An elbow flange is a combination of a standard elbow and a
standard flange fabricated into a single fitting. Elbow flanges are
typically used when the minimum leg lengths for either the standard
elbow or standard flange cannot be maintained. Minimum leg
lengths are listed in Table 23 and Table 24.
ote:N All dimensions are to the centerline of the Pow-R-Bridge.
