Stiff Nylon Mailbox Brush Seal

Measures 30.00 × 3.00 × 0.50 cm (11.79 × 1.18 × 0.20 in). Features densely packed black nylon bristles bonded to a rigid metal backing strip, ensuring even pressure distribution across the full length. The nylon grade is specifically chosen for stiffness and elastic recovery, resisting permanent deformation from daily lid operation. This enables sustained contact with the mailbox lid edge, providing ongoing wiping action and improved resistance to wind-driven rain, airborne dust, and insect ingress. Works reliably in both sheltered indoor vestibules and fully exposed outdoor settings typical of UK terraced houses, semi-detached homes, and apartment blocks. Supplied as a two-strip pack to accommodate varying mailbox configurations and extend service intervals.
