Tired of unwanted visitors in your yard? These KKUYT anti-climb spikes are the humane solution you've been looking for! This 12-pack gives you about 17 feet of coverage to protect your property from intruders - both animal and human. Made from high-quality polypropylene plastic that's durable and weather-resistant, these spikes won't deform in strong sunshine or corrode like metal spikes often do. Each strip measures 16.9 x 1.5 x 1.4 inches and can be snapped to fit every 5.6 inches, making them adaptable to any fence length or boundary. Installation is super easy - just use screws, nails, or strong zip ties through the 18 pre-drilled holes on each strip. They work effectively to deter cats, dogs, raccoons, birds, and even human intruders from climbing over your fences, walls, roofs, railings, gates, or sheds. The plastic construction is much safer than barbed wire or razor wire - it discourages climbing without causing serious injury to animals or people. The brown color blends well with most outdoor surfaces, and you can even paint them with plastic-specific paint if needed. Perfect for securing your yard perimeter, garden boundaries, patio areas, windows, or any place where you want to prevent unauthorized access. They're reusable and maintain their effectiveness through all weather conditions and seasons. While they work great for most animals, they're not recommended for deterring squirrels who might still find ways around them. If you're looking for an affordable, humane way to protect your property without the danger of sharp metal barriers, these plastic anti-climb spikes deliver reliable security with peace of mind.
