Focusing on Risks Prevention at the Letter Plate Point
These groundbreaking gravity-powered solutions are designed to repel liquids and block most hazards from entering the letterbox while providing the safest means of traditional mail delivery and draught proofing.
With IdealGuard™/T innovative product fitted at the back of the letterbox it would be difficult to introduce liquid and solid non-mail items through the letter plate, and impossible to access locks or extract items from the property. The introduction of liquid will cause it to be forced out by gravity rather than remain inside.
Most lawful mail items can be easily deposited without the need for folding or any additional effort. No capacity restrictions on repeat mail deliveries.
When necessary, for example, for security reasons, or when the property is left unoccupied, some models allow completely blocking access through the mail slot.
Compatible with any door material and door thicknesses, IdealGuard™/T series products provide simple solutions to improve compartmentation in buildings with flats and protection of the fire escape route.
