These super tough cages are extremely effective in reducing malfunctions and high maintenance costs where vandalism or accidental damage to security PIR detectors is prevalent.
Guards are constructed of 9-gauge steel wire with corrosion-resistant polyester coating. They are designed so there is no interference with the operation of the protected unit. Sizes to fit virtually all PIR detectors.
Installation fixings are provided, but where additional security is required, tamper resistant screws and matching bits are available. As all STI protective cover, these Motion Detector Damage Stoppers® are backed by a lifetime guarantee against breakage in normal use.
