Black Nylon Brush Seal Strip

Dimensions: 30.00 × 3.00 × 0.50 cm (11.79 × 1.18 × 0.20 in). Constructed with stiff black nylon bristles mounted on a supportive metal core for structural integrity and consistent pressure distribution. The bristles maintain upright positioning after repeated compression due to their high recovery performance. Designed for reliable contact along the mailbox lid’s closure edge, enabling continuous debris wiping and enhanced exclusion of dust, rain, and insects. Suitable for both indoor and outdoor use across common UK mailbox types — including brick-built, aluminium, and timber enclosures. Each pack contains two brush strips, allowing full coverage on standard dual-flap or larger single-lid mailboxes, or extended replacement life.
