A closure restraint system for providing security of an enclosed space by denying access into the interior of enclosed space or vice versa denying access to the exterior of the enclosed space. Access to said enclosed space is provided by some type of closure, typically a door, gate or access panel. The closure restraint system is mounted as and operates as a single unit with the second support plate being swiveled along the frictionally-restrained axis of the swivel shaft to the locked position with the closure closed. As the closure is attempted to be opened it is held ajar in the locked position; a line of sight or access cannot be obtained into or out of the enclosure; therefore, it does not allow the restraint system to be defeated.
