Abstract
A flexible barrier system is described that can be lowered or raised from a remote location using an accompanying remote control device which is either lockable or not lockable. The motor and mechanics used to raise and lower the chain are modular for easy repair and replacement, and enclosed in a protective covering in order to protect them from damage or tampering.
