Bird-defense spikes are a barrier that makes flying and sitting on simbas and projections difficult. So you keep birds like pigeons and swallows away without harming them. The 400 spikes are made of stainless steel for outdoor use. They can be inserted one- or three-row into the 10 plastic carrier strips. These are connected by a click system. The bars can be divided at the predetermined breaking points. This allows you to adjust the length individually. Holes are pre-drilled in the strips for easy screwing or fixing with cable ties. They can also be attached with mounting adhesive.This text is machine translated.
