Claim 0:
1. A closure system comprising:
a closure, wherein the closure is configured to at least partially obstruct an opening in an extended state and allow access through the opening in a retracted state, the closure comprising:
a plurality of slats;
a bottom interface, wherein the bottom interface comprises a first portion and a second portion that extends horizontally away from the first portion; and
a bottom bar coupled to the second portion of the bottom interface, wherein the closure deflects by a first deflection distance when a vertical force is applied to the closure; and

a strap coupled to the first portion of the bottom interface and at least two slats of the plurality of slats that are closest to the bottom interface, wherein the closure with the strap coupled thereto deflects by a second deflection distance when the vertical force is applied to the closure, wherein the first deflection distance is at least 100 percent more than the second deflection distance, wherein the closure is movable between the extended state and the retracted state while the strap is coupled to the first portion of the bottom interface and the at least two slats of the plurality of slats.
