Calvana 4 Inch Slope Drainage Grate Cover, Yard Drain Emitter Alternative to Pop-Up Drain, Fits 4" SCH 40 SDR 35 Corrugated Pipe, Downspout & Sump Pump Discharge Drain Outlet, Green

["Designed As An Alternative To Pop-Up Drain Emitters: Unlike pop-up drain emitters that rely on water pressure to open, this slope grate design allows continuous water discharge. Helps reduce issues where traditional emitters may stay closed or freeze in place.","Slope Design Improves Drainage On Uneven Ground: Angled grate structure directs water flow along sloped or uneven surfaces. Compared to flat drain outlets, it helps reduce standing water and improves overall drainage performance.","Compatible With Common 4 Inch Drain Pipes: Fits standard 4 inch SCH 40, SDR 35 and corrugated pipes. Manual-fit design allows flexible installation for yard drainage systems, downspout extensions and sump pump discharge lines.","Green Open Grate Structure Helps Reduce Clogging: Grate opening allows water to flow while limiting leaves and debris entering the pipe. Suitable for outdoor drainage areas where debris buildup is common.","Tool-Free Installation With Easy Maintenance Access: No glue or screws required. Connect directly to the pipe and adjust when needed. Openable cover design allows quick inspection and cleaning of the drainage line."]
