This letterbox seal and brush unit in white is made for fitting onto doors to help reduce draughts and prevent dust from entering around the letterbox opening. The no-flap design is intended for installations where constant access for mail is preferred and where standard external flaps may be more likely to get damaged or become unsuitable.
It is commonly installed on timber, uPVC, or composite doors by joiners, carpenters, or maintenance staff in both residential and commercial properties. The seal can be fixed with typical hand tools as part of general door improvements or during weatherproofing work, providing a discreet finish that matches a range of door styles.
