This gutter brush is a simple yet effective protection with significant advantages: on one hand, it prevents the clogging of the rain gutter caused by falling leaves or needles. The long and stiff plastic bristles stop leaves and small twigs from accumulating in the gutter, allowing rainwater to flow freely. This eliminates the need for constant gutter cleaning. On the other hand, this gutter brush provides reliable protection against martens. The animals, with their sensitive paws, avoid the hard bristles. Thus, not only gutters but also photovoltaic systems, which animals like to seek shelter under, can be protected from martens and birds. Simply place it in your gutter, and you're done. No additional fastenings are needed, and especially without the need for an expensive handyman, you get an effective and cost-efficient protection against leaves, twigs, and animals. The gutter brushes are particularly suitable for half-round gutters and are available in various sizes. The gutter brushes consist of two twisted galvanized metal wires and polypropylene fibers.
