> represents direction of closure and number of zippers. In sewing zipuers, closed 

 sliders must butt against adjacent base plates, (j)o'te vertical zippers on skirts 

 reverse on opposite sides and ends (AB and BA)^ because end-skirt zippers must close 

 in same direction when large panels are used./

Erection of Cage 



The framework of the cage should be erected with side skirts in position as early 

 in the season as practical, well in advance of the development of the crop. The turn- 

 buckles should be at the top of the inner line of posts (fig. 5). (Note that position of the 

 corner guy wires puts the maximum downward pressure at the corner. ) Reversing the 

 internal guy wires would cause more downward pressure to be applied on the outside 

 line, but the recommended position has proA^ed adequate and the wires produce minimum 

 obstruction. Also, the second line of posts would have to be anchored if the guy wires 

 were reversed. The looped ends of the wires must be on the opposite side of the slip- 

 on fittings attaching the outside and inside posts. 



After the framework has been oriented to the area and alined, all Allen screws, 

 which should have knurled tips , MUST be checked for firm attachment to all pipe 

 lengths. One loose joint could place undue stress on the entire cage under high wind 

 velocity.
