Stop climbing with MAXguard Fence and Wall Spike Strips that guard against trespassers and nuisance animals from climbing over fences or walls by providing a strong visual and physical deterrent using a single row of 1-1/2 in. (3.9 cm) high blunt tip metal spikes. Easily installed onto the tops of fences or walls made of brick, block, stone, iron, chain-link, wood or vinyl, all without sacrificing aesthetics. The spike strips are contoured to fit onto most walls or fences with a flat top 1-in. (2.54 cm) or more in width, or any chain-link fence with a 1-3/8 in. (3.5 cm) or 1-5/8 in. (4.2 cm) horizontal top-rail. Fence and Wall Spike Strips are U.V. and impact resistant, withstand extreme temperatures, and can be painted to match any decor. While sharp aggressive products such as barbed and razor wire are not typically allowed by homeowners associations and most municipal laws, Fence and Wall Spike Strips are specifically designed to comply with such rules, meaning no hassle for property owners but plenty of hassle for trespassers that may be tempted to climb over walls or fences around your yard. Installation is as easy as cutting the spike strip to the desired length using any fine-toothed saw, applying a bead of the included industrial-strength adhesive along the entire length of the backside of the strip, and then placing the strip into final position. 24 hours later the strips are virtually impossible to remove.
