A configurable mounting system for supporting plumbing conduits on a boom arm of an agricultural sprayer includes a mounting base and an elongated platform portion. The platform portion has a front face, a rear face, and opposing side faces, the front face forming a base interface. The mounting system also has at least one conduit bracket having a conduit retaining portion and a bracket interface configured to slidingly engage and lock with the base interface of the mounting base. The mounting system also has an extension member mounted on the distal end of the mounting base. The extension member forms an extension to the platform portion increasing an area capable of receiving conduit brackets. The mounting system also has a horizontal spacer positionable between the mounting base and the conduit bracket that increases the separation between the mounting base and plumbing mount.
