A modular railing baluster system includes a mounting device having an upper connector that may connect to an upper railing or other upper support surface and a lower connector that may connect to a lower railing or other lower support surface. The mounting device may include various shapes and may secure various objects within the railing system, such as a picture frame or similar display article, as one example. The system further includes one or more offset balusters that may be arranged in a symmetrical mirrored orientation on opposing sides of the mounting device. The offset middle portion of the offset baluster may maintain even spacing between the offset baluster and the mounting device. The system may further include additional vertical balusters for integration into an existing railing system and customized spacing of multiple mounting devices along the length of the railing system.
