Bird Beak with Mesh

Bird beak terminals with mesh for spiral ducting, available in all 24 diameters from 80mm to 1000mm, with every size up to 250mm stocked except 224mm. The bird beak is the classic through-wall duct termination: its angled, downward-facing opening sheds rain naturally while the mesh screen keeps birds, rodents and windblown debris out of the ductwork.

The standard wall termination

Wherever a supply or extract duct exits through an external wall, a bird beak finishes the penetration properly — no rain driving into the duct, no nesting material finding its way in, and a clean galvanised finish on the face of the building. The shape also directs discharge slightly downward and away from the wall, reducing staining above extract points. Fit it to the duct like any other spiral component, then seal the wall penetration around the duct.

The full spiral series is covered: 80, 100, 125, 150, 160, 180, 200, 224, 250, 280, 300, 315, 355, 400, 450, 500, 560, 600, 630, 710, 762, 800, 900 and 1000mm. Every size up to and including 250mm except 224mm is held in stock; 224mm and larger sizes are made to order. For vertical roof terminations see the weather hat and jet cowl. Stocked sizes despatch next day when ordered by 3pm.
