30cm Nylon Mailbox Seal Strip

Precisely sized at 30.00 × 3.00 × 0.50 cm (11.79 × 1.18 × 0.20 in), this brush seal features black nylon bristles fixed onto a robust metal carrier. Delivers stable, linear pressure along the full length to ensure uninterrupted wiping and sealing action as the mailbox lid closes. The nylon exhibits high stiffness-to-flex ratio and excellent recovery, preventing bristle collapse or leaning even after months of UK-use cycling. Effective in minimising ingress of fine particulates, light precipitation, and crawling pests — particularly beneficial in coastal, urban, or rural locations with elevated wind or insect activity. Fits standard UK mailbox dimensions and mounting profiles, including recessed, surface-mounted, and heritage-style enclosures. Supplied as a pair for complete sealing coverage or phased maintenance planning.
