Overhead closure with tube and hook end lock

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.

• 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
