The letterbox guard is effectively a security Letterbox Cowl which fits over the inside of the letterbox on your street door.


The product is designed to help protect against car key fishing attack by thieves, who use hook and rod devices poked through your letterbox to steal car or housekeys from a nearby shelf or hook, ...which can then be used to steal your car from your driveway or burgle your home!


The product is also great for preventing curious eyes peering at you through your letterbox
