The Hedgehog GutterClip keeps the Hedgehog Gutter Brush securely in place in gutters within all kinds of challenging environments; low hanging, flat roofed, gutters with no tile nose overhanging and those located in high wind areas. DISCLAIMER - There is always a chance that the gutter brush will come loose and fall out during high winds or when interfered with by birds. We would suggest 1 clip is used at ever 1m interval.
