Gutter Clamps
21mm jaw for gutters and vertical flanges (such as this Brise Soleil). A polypropylene spacer can be used to spread the pressure of the bolt on plastic gutter.
Beam Clamps
21mm jaw for horizontal flanges.
Rail Clamp Posts
Can be screwed in place directly or used with Rail Clamps to proof pipes and rails.
Threaded Posts
For tops of signs etc. install through 4mm hole.
Drilled Rods
Installed horizontally above ledges to avoid multiple holes on ledges. Drill 6mm hole 95mm above the ledge and tap the rod in. Fit anti-perch wires above and counter-tension wires at ends.
Multi-Headed Posts
Installed using 6.5mm holes and Anchor Rivets, can be used for smaller ledges
Special Fabrications
Sometimes individually designed brackets are required e.g. to avoid holes in tops of parapets, posts can be welded onto shaped strips of stainless steel
Roof Ridge Brackets
Triangular - install with Avifix and Blind Anchor Rivets (drill 6.5mm hole into the ridge tiles or mortar, push in the rivet, then knock in the plastic nail). Half Round – can also be clamped.
Counter-tension the end brackets with wires secured to a split pin.
Pigeon Stick-on System
Never drill through metal flashing – use stick on system instead
Remove the oil coating (with Soudal Surface Cleaner or Surface Activator) from gluing area on new lead; remove patination from old copper/lead by abrasion; scratch all lead surfaces for better adhesion.
Wipe underside of Stick-on-Base and metal surface with Surface Activator; dry for 5 minutes; then install straight away. Use Avifix adhesive, pressing and jiggling on firmly to about 1mm glue thickness, allowing rivets of glue to form through the holes.
Let the glue cure prior to wiring up the system in the same way as for masonry. Curing time varies according to temperature but is at least 24 hrs. This system should not be installed in the wet or in temperatures below 5°C.
