5m x 5m cage would be made up of 4 x 2 5m units.
Peak on roof pushing out.

Made of coated metal welded wire peak protector guard forms at the ideal lengths and angles for maximum protection and security.
A 4 in 12 pitch means the roof rises 4 inches for every 12 inches of horizontal distance.
Roof slope is expressed as the ratio of a roof s rise vertical distance to each foot of run horizontal distance.
Calculate the roof pitch.
