The RL1200 Square Post Railing system combines solid aluminum square posts with glass, cable, or panel infill options to create a contemporary, architectural guardrail solution for decks, balconies, walkways, and stairs. The structural aluminum posts bolt directly to the deck framing or concrete substrate, providing a rigid, reliable foundation. Clean square geometry and a range of infill choices make the RL1200 a versatile system that complements modern and transitional architectural styles equally well.
