Steel downpipes, like PVC, should be clipped at maximum 1.8m centres and below any swan neck. Our downpipe clips are extremely well engineered to ensure a secure fit. Using a 12mm masonry bit, drill the brickwork and insert the rawlplug supplied with the clip. Then, using either a pair of pliers or a small adjustable spanner, insert the metal screw into the plug. Next, screw the metal backplate onto the protruding thread, and secure the pipe clip with the brass key provided.
