Spikes needle strips from Bird-X are designed to keep birds off roofs, ledges, gutters, windowsills, statues, beams, trees, air conditioners, awnings, signs and cables. The spikes project from the base creating a 4.5-in. pointed barrier that prevents birds from landing. Spikes are made of ST302 hard surgical grade stainless steel and the base is UV-inhibited polycarbonate. The flexible base installs on regular linear surfaces, plus concave or convex curves and irregular surfaces. The modules are 2-ft. long and each strip locks into the next. Excess length snaps off and the metal projections come pre-assembled in the base.
