Abstract: A modular conduit securement system includes a back bracket having, in transverse cross-section, polygonal back surface proportioned for securement to at least one constructional surface. Such back bracket includes a front surface having resilient nesting elements having a partially opened-face geometry. The back bracket further includes, along each proposed inner transverse edge, first complemental coupling elements. The conduit, proportioned for complemental coupling to the nesting elements of the back bracket, is provided. Further provided is inner front plate proportioned, in transverse cross-section, for complemental engagement with the first complemental coupling elements to thusly provide a modular conduit system formed by the insertion of the conduit into the nesting elements and by the coupling of the front plate over the first coupling element of the back bracket.
