5 x Hedgehog Gutter Brush Guard 100mm Black 4m Clear Clean Leaf Debris Free Gutters Stop gutters and ground drainage channels becoming blocked by fallen leaves, and twigs. The Hedgehog has been designed to prevent leaves clogging gutters and drains, keeping them clear for years meaning no more time-consuming and dangerous maintenance work. Protection from blockage will prevent subsequent damaging water overflow, saving time and money in the long term. No protection - gutters easily fill up with leaves and twigs which means water cannot flow freely and builds up. When water overflows, seals will deteriorate and leaks will form in joints and down pipes. Gutter grill - leaves and debris settle on the grill causing water to run over the side while sediment builds up in the gutter.
