Tower Guard deters gulls, cormorants, vultures, osprey, hawks, owls and other large birds. It creates both a visual and physical barrier for railings and flat surfaces. When birds view TowerGuard, they see that it takes away the perch and is too small and unstable to land on. By pulling a simple pin, the posts can be easily removed from the bases for maintenance where access is important. The product is made from the same plastic that the telecom industry uses for its outdoor boxes. It’s well documented to withstand UV degradation for many years. For sensitive applications, such as radar and radio sites, the TowerGuard system can be installed without metal parts.
