The bottom bar locks into position with two locks at the bottom left and bottom right in order to keep the blind fully down and secured. If you are outside of the outdoor area and you would like to be able to unlock the blind, a “reverse lock” addition  is available to the centre-lock-release system. This will allow you to operate the centre-lock-release which faces the inside of your entertaining area, although you are on the outside.   These locks are not designed for use as a security measure. The blind system should not be used as barriers for babies or children. The centre-lock-release mechanism is not child proof.
