Material: The gutter strainer is made of 304 stainless steel, which is corrosion-resistant, anti-clogging, and durable. It allows for fast draining and is sturdy for long-term use. Dimensions of the gutter filter: 124mm in the longest diameter and 98mm in the bottom diameter (may have 2-5mm variation due to manual measurement), suitable for downpipes up to 110mm in diameter. Raised hollow design: The elevated hollow structure helps prevent clogging by effectively catching debris and keeping leaves and large particles from covering the drain opening. Easy installation: The gutter filter features a plug-in design. No additional tools are required. Simply insert it directly into the PVC drain pipe and push into the proper position for a secure fit. Wide range of applications: Suitable for outdoor drain pipes, balcony floor drains, roof drainage systems, swimming pool vents, and other drainage outlets. Effectively filters out weeds, dead leaves, and debris while providing protection for small animals.
