Stop climbing with MAXguard Wood Fence Spike Strips that guard against trespassers and nuisance animals from climbing over wood fences 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. The U-shaped spike strips are easily installed onto the tops of most wood fences with vertical slats, 5/8-inch (1.59 cm) through 3/4-inch (1.91cm) in thickness (standard). Wood Fence Spike Strips are UV and impact resistant, withstand extreme temperatures, and can be painted to match any decor, all without sacrificing aesthetics. While sharp aggressive products such as barbed and razor wire are not typically allowed by homeowners associations and most municipal laws, Wood Fence 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.
