13. A tube and hook locking system comprising:

a guide assembly comprising a wall mounting element fixed to a guide extrusion;

the guide extrusion comprising a closure guide first section and a closure guide second section; and

a hook and tube assembly contained within the closure guide second section;

wherein the tube and hook assembly comprises an elongated member having a first end operatively attached to an actuator and a second end comprising a rotation point; and

at least one hook attached to the elongated member; and

the guide assembly comprises a guide assembly slot located such that when the tube and hook assembly is actuated, the hook passes through the guide assembly slot to restrictively engage a closure.

14. The locking system of claim 13 further comprising wear strips mounted to the closure guide first section.

15. The locking system of claim 13 further comprising a guide trim attached to the guide extrusion.

16. The locking system of claim 13 wherein the elongated member comprises separable segments.

17. The locking system of claim 13 further comprising a rotation point receiving member fixed to the guide assembly.

18. The locking system of claim 13 wherein the rotation point comprises a ball plunger.

19. A closure system comprising:

a first and second guide assembly;

a closure comprising a closure material and a first and second closure end strip fixed to a respective first and second side of the closure material; the closure fixed to a counterbalance assembly supported by securing members; the first and second closure end strip movably contained within the respective first and second guide assembly;

an operator operatively attached to the counterbalance assembly;

a first and second tube and hook assembly contained within a respective first and second guide assembly and reversibly restrictively received by the respective first and second closure end strip; and

a bottom bar assembly fixed to the closure, the bottom bar assembly comprising a first and second bottom bar tab assembly extending from a respective first and second bottom bar end;

wherein

the first and second respective closure end strip are not thicker than the closure material;

each guide assembly comprises a wall mounting element fixed to a guide extrusion; the guide extrusion comprising a closure guide first section having wear strips to receive a closure end strip and a bottom bar tab assembly; and a closure guide second section to contain a tube and hook assembly;

a guide strip is attached to the guide extrusion; and
