Use BirdSlide on ledges, eaves, angle irons, I-beams and most "L" shaped ledges where total exclusion is the goal. BirdSlide is sold in five-foot sections. BirdSlide completely protects the ledge against all bird species; they simply can't get a grip and slide right off the ledge. When color matched to the structure, BirdSlide usually looks like it's a part of the building. It comes in gray or beige, but can be primed and painted to match any color. Easy to Install: For ledges six inches wide, the flat base simply glues to any clean surface using Bird Barrier bond. For narrow ledges the fin can be trimmed down; for wider ledges an extension can be added. BirdSlide can be screwed to wood. Made from UV-stabilized polycarbonate. Two-year warranty against UV breakdown. Paint the product to extend its life.
