- Semi-flexible round topped (to prevent injury to
birds) UV stabilised polycarbonate bayonet spikes,
100mm high, set diagonally
- Spikes 35mm apart but diagonal setting reduces
effective gap to 28mm
- UV stabilised polycarbonate base strips are 333mm
long, 20mm wide and 4mm thick
- Receiving space for 'jigsaw' type press attachment
- Slightly curved ends to allow joined strips to
follow slight curves in receiving surface. (E.g. certain
canopies, balconies etc.)
- Grooves to enable the strip to be snapped off for

bird deterrents are UV-stabilised polycarbonate anti-perching
devices which prevent large birds, such as feral pigeons,
jackdaws, crows and most seagulls, from perching and
roosting on building ledges, beams, pipes and ridge-tiles.
bird deterrents are one-piece constructions, so no assembly
is required and no corrosion or rusting occurs.
bird deterrents are non-conductive. They will not interfere
with electronic security systems, or radio signals and
transmissions and, unlike metal spikes and wires, they
will not attract lightning during thunder storms.
Each piece of "Flock-Off"
is 333mm long with 6 pairs of spikes. The spikes are:-
- 100mm in height.
- 55mm apart, but set diagonally, thereby reducing
the effective gap to 28mm.
- Splayed, giving a depth coverage of 65mm.
- Round-topped and semi-flexible, to prevent injury
to birds. (a concern of the environmentalist lobby.)
The base of each piece of "Flock-Off"
is 20mm wide and 4mm thick and has the following features:-
- 6 holes for fitting with screws or masonry nails.
- 4 snap-off grooves to facilitate precise installation.
- Curved underside for closer fitting to pipes and
- "Jig-Saw" type connections (male and
female) for joining pieces together.
