Abstract
Embodiments of the present invention provide modular grid systems for use with aperture-forming devices. The modular grid system includes a plurality of modular grids, wherein each modular grid includes an outer frame, an outer partial ring coupled to the frame, and at least one inner partial ring coupled to the outer partial ring via at least one securable connection, wherein the outer partial ring and the at least one inner partial ring form arcs of greater than 180 degrees but less than 360 degrees. Each modular grid is coupled to an adjacent modular grid. In some embodiments, the outer frame comprises a removable bar. In some embodiments, the plurality of modular grids are oriented in the same direction. In some embodiments, the modular grid is configured to couple to an aperture-forming device, where the aperture-forming device has a diameter ranging from 2 to 6 inches.
