It is recommended that the longitudinal pipes butt against each other at their ends, 

 which meet at the center of the sleeve fittings, and that the transverse pipes butt against 

 the sides of the longitudinal pipes. Once the framework is alined with the side skirts 

 in place, stakes should be driven to anchor the ground rail firmly to the ground, one at 

 each post and two at the corners. Note that the direction of tension on the corner guy 

 wires tends to pull down on the corner posts (fig. 5). 



Poles used to roll the screen panels can be cut from 2-inch knot-free lumber, 

 which should be at least 2 feet longer than the width of the panels. The panels must be 

 rolled starting at the slider closure end with the sliders down for inside closure, so 

 that the pinned end of the zippers will be to the outside of the roll for attachment to the 

 side skirts when erecting the cage. 



Proper procedure for erecting the cage (panels diagramed in fig. 6) is as follows: 

 Place the first panel roll over the first three lines of posts and unroll about 1^ zipper 

 lengths. Attach the pin ends and close the zippers to attach the panel to both the end 

 and side skirts. Place panel 2 on lines 3,4, and 5. but unroll slightly less than panel 

 1 and attach zippers. Follow with panel 3 placed on lines 5,6, and 7, unrolling slightly 

 less than panel 2. All zippers must be attached to the appropriate skirts and top panels 

 in sequence as the top panels are unrolled. Follow the same sequence as additional 

 panels are added. 



If a mistake is made in rolling the panels onto the poles, it is best to lay the panels 

 out on flat ground and reroll rather than attempt to pull the panels across the frame- 

 work after they have been unrolled. It is important that all zippers be attached in 

 sequence during the unrolling of the screen panels. 



The cage is dismantled in reverse of its assembly, and the panels are rolled 

 with the closure ends of the zippers on the inside of the rolls. 



The rolled panels are stored on a demountable rack 2 feet wide. 24 feet long, and 

 12 feet high, fabricated with short lengths of |-inch pipe and the slip-on fittings. Flange 

 plates are bolted at 20- inch intervals to four lengths of 3- inch channel iron spaced 6^ 

 feet apart and anchored to the building wall. Tees and flange plates provide rigid 

 attachment of the short lengths of pipe for supporting the panel rolls and for obtaining 

 the required height of the rack. The rolled panels MUST be stored in a mouse-proof 

 building. The pipe is stored out of doors. 



It is important that all panels be of a dimension that will fit the framework of the 

 cage, so that miscellaneous lengths of pipe will not be needed. If mistakes have been 

 made in the basic layout of the cage, it may be necessary to have some odd lengths of 

 pipe at one end of the cage.
