One or more rows of thin wire, tensioned with springs, are held just above the surface being protected. Steel components are 316 grade stainless steel.
The birdwire system is only for bird proofing against pigeons and gulls - it is not effective against smaller bird species.
Unless applied by very experienced installers, birdwire should only be used in light pressure areas.
Uses: parapets, ledges, signs, beams, pipes etc.
(Culling of resistant birds may be necessary soon after installation).
