The cord lock is an important part of the blinds and helps in controlling the raising and lowering of the blinds. It works by allowing the user to secure the cord at the desired height, thus keeping the blinds in place. A cord lock consists of a mechanism that locks and unlocks a cord to maintain the blind's position. When the cord is pulled, the lock engages to hold it in place, preventing the blind from accidentally falling or raising. This feature enhances privacy, light control and convenience, allowing users to easily adjust the blinds to their preferred height and angle.
