A closure end strip is fixed to a closure end and received by a closure guide first section. A rotatable tube and hook assembly run vertically within a closure guide second section. When rotated to a locking position a hook member of the tube and hook assembly rotates through a slot cut in the guide and through a cutout in the closure end strip to restrictively engage the closure. ## Claims ### Claim 1 A closure system comprising: a guide assembly; a closure mounted to a supported counterbalance assembly and movably contained within the guide assembly; an operator operatively attached to the counterbalance assembly; and a tube and hook assembly contained within the guide assembly and reversibly received by the closure; wherein the guide assembly comprises a wall mounting element fixed to a guide extrusion; the guide extrusion comprising a closure guide first section to receive the closure and a closure guide second section to contain the tube and hook assembly; and 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; the guide assembly further comprising a guide assembly slot located such that when the closure is closed and the tube and hook assembly is actuated, the hook passes through the guide assembly slot to restrictively engage the closure. ### Claim 2 (depends on 1) The closure system of claim 1 further comprising a bottom bar assembly fixed to the closure, the bottom bar assembly comprising a tab extending from an end which inserts into the closure guide first section, a first and second closure material mounted element mounted to a first and second side, respectively, of the closure material; wherein a retaining extension extends from each closure material mounted element to slidingly receive and retain a bottom bar. ### Claim 3 (depends on 2) The closure system of claim 2 wherein the each closure material mounted element is a curved washer. ### Claim 4 (depends on 1) The closure system of claim 1 further comprising wear strips mounted to the closure guide first section. ### Claim 5 (depends on 1) The closure system of claim 1 further comprising a guide trim attached to the guide extrusion. ### Claim 6 (depends on 1) The closure system of claim 1 wherein the closure comprises a closure material and a closure end strip having a closure end strip cutout, the closure end strip fixed to a side of the closure material and received by the closure guide first 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; at least one hook attached to the elongated member; and the guide assembly further comprises a guide assembly slot located such that when the closure is closed and the tube and hook assembly is actuated, the hook passes through the guide assembly slot and closure end strip cutout. ### Claim 7 (depends on 6) The closure system of claim 6 wherein the closure end strip cutout is larger relative to the guide assembly slot and the closure end strip is not thicker than the closure material. ### Claim 8 (depends on 1) The closure system of claim 1 wherein the closure comprises a closure material end having a closure material end cutout; 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; at least one hook attached to the elongated member; and the guide assembly further comprises a guide assembly slot located such that when the closure is closed and the tube and hook assembly is actuated, the hook passes through the guide assembly slot and closure material end cutout. ### Claim 9 (depends on 8) The closure system of claim 8 wherein the closure material end cutout is larger relative to the guide assembly slot. ### Claim 10 (depends on 1) The closure system of claim 1 further comprising a rotation point receiving member fixed to the guide assembly. ### Claim 11 (depends on 1) The closure system of claim 1 wherein the elongated member comprises separable segments. ### Claim 12 (depends on 1) The closure system of claim 1 wherein the tube and hook assembly comprises a tube having an orifice with the hook passing therethrough. ### Claim 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. ### Claim 14 (depends on 13) The locking system of claim 13 further comprising wear strips mounted to the closure guide first section. ### Claim 15 (depends on 13) The locking system of claim 13 further comprising a guide trim attached to the guide extrusion. ### Claim 16 (depends on 13) The locking system of claim 13 wherein the elongated member comprises separable segments. ### Claim 17 (depends on 13) The locking system of claim 13 further comprising a rotation point receiving member fixed to the guide assembly. ### Claim 18 (depends on 13) The locking system of claim 13 wherein the rotation point comprises a ball plunger. ### Claim 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 each closure end strip comprises a closure end strip cutout each guide assembly further comprises a guide assembly slot and each 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; such that when the closure is closed and the tube and hook assembly is actuated, a respective hook passes through a respective guide assembly slot and respective closure end strip cutout. ### Claim 20 (depends on 19) The closure system of claim 19 wherein the respective closure end strip cutout is larger relative to the respective guide assembly slot. ### Claim 21 (depends on 19) The closure system of claim 19 further comprising a rotation point receiving member fixed to the guide assembly. ### Claim 22 (depends on 19) The closure system of claim 19 wherein the elongated member comprises separable segments. ### Claim 23 (depends on 19) The closure system of claim 19 wherein the tube and hook assembly comprises a tube having an orifice with the hook passing therethrough. ### Claim 24 (depends on 19) The closure system of claim 19 wherein the first and second bottom bar tab assembly each inserts into a respective first and second closure guide first section;
