You must install the cleats no lower than 1.5 metres to the floor and the cleat must be able to take all of the cord when the blind is in the fully raised position. If one cleat cannot take all of the cord install two cleats, one above the other, approximately 15cm apart or sufficiently apart to ensure that all of the cord can be accumulated on the cleats and no part of the cord or acorn is lower than 1.5 metres to the floor.
