Flange Dimensions
Weld 42: The weld leg of the studded outlet perimeter weld.
Weld 44: The weld leg of the studded outlet weld at the finished opening of the host shell.
Diameter of Reinforcement: The limit of reinforcement measured parallel to the studded outlet axis. This is a calculated value determined per UG-40(b). The result may be reduced by the user, but it may not be increased beyond what is calculated per UG-40(b). Reducing the value results in a lower available area in the reinforcement calculations and makes meeting UG-37 reinforcement requirements more difficult. For example, openings in close proximity may not have overlapping limits of reinforcement, so the code would require a reduction in this value and would thereby increase the difficulty of meeting UG-37 requirements. See UG-42 for more information.
