Abstract: The present invention comprises a modular connector pipe screen for a catch basin having a plurality of screen segments and a deflector screen. The screen segments may be stacked and adjoined side-by-side wherein the segments are secured together with only fasteners and without any separate frame structure for connection or support. Accordingly, each screen segment is comprised of a single perforated panel having a bottom flange, and at least one of an upper flange, and a side flange which provide integrated structure support as well as surfaces to which the single segments can be fixed together. When stacked, the bottom flange of a first screen segment may be connected to the upper flange of a second screen segment through a fastener or screen segments may be adjoined side-by-side and fastened at the side flanges. Additional screen segments may then be added to create different shapes for various installation needs.
