BIRDWIRE STANDARD INSTALLATION
Features
- Discreet system
- Favoured by architects
- Not suitable for heavy pressure sites

Specification
- Posts, Split Pins and Brackets stainless steel
- Pigeon Birdwire 0.45mm stainless steel 1 x 7 wire rope coated with UV protected nylon to 0.7mm
Drill Holes
Pigeon Birdwire on Masonry
- Drill 6.5mm hole, 25mm deep
- 1st row holes 20mm in from edge
- 2nd row holes 45mm back medium or 55mm back light pressure
- Subsequent rows then 65mm medium and 75mm light pressure
- Holes max 1.5m apart along rows, can be less when going round curves
- Stagger holes from front to back - helps prevent pigeons landing on neighbouring springs and dropping down between wires

Clean dust away

Posts
- Tap in anchor rivet. The dome shaped rivets help reduce water ingress; Avisil in the hole can help further reduce this if required
- Knock posts into holes. Use 120mm (or 130mm double headed for extra protection) posts for front row, 150mm for rows behind.


Split pins
- For walls at ends of run use horizontal hole, anchor rivet and split pin

Springs and Wires
- Cut Birdwire to about 100mm longer than gap; thread a Crimp on; pass wire through hole in Post or Split Pin and back through Crimp. Fasten Crimp close to post with Cut & Crimp Tool, then trim excess wire
- Hook Spring into eye of next post, making sure it is twisted fully on; fit on a Crimp; pull wire until Spring just tensions; slide Crimp up to Spring and fasten. When runs are less than 1.5m springs not required on every run
- Bend leading edge posts out so that wire is directly above ledgeedge, and gap between first and second parallel rows is 65-75mm



Gulls
Gull Wire
- Installation is similar to that for pigeons, but use larger, heavier-duty components
- Black Headed Gulls - 180mm x 4mm posts, ideally 2m apart, 0.96 mm diameter wire max 90mm apart, 1mm ferrules
- Herring and Lesser Black Backed Gulls - Gull Post Plugs with 200mm x 5mm Gull Posts ideally 3m apart; 0.96mm wire max 125mm apart, 1mm ferrules
