This is a 2 wall / half pack - \ Covers half  of the awnings open area. (4.5m of walls)
 
Set up on each panel is fast also (under 30 seconds per panel). Zippers are over-sized YKK and canvas used is very heavy-duty all round. (The heaviest of the awnings we stock). Any wall fits anywhere - even sideways.
 
Comes with a bag to store them in when not in use.
 
While the awning Walls are listed with multiple color options below - (These walls  are imported from South africa) and Typically we don't always get both Green and Grey in Both Sizes (2.1 and 2.4 ) colors each shipment... If your deadset on a particular color combination -Please order a way ahead of required time. 
 - and if your not terribly fussy on Grey lor Green Canvas - Please select 'Any Color' from the color options for a much speedier collection / shipping date. 
 
To measure the height of the walls you require: 
Open your Ostrich wing awning, measure from the valance zipper on the outside edge of the awning ,Where the walls would zip on - to the ground. If the measurement is close to 1950mm - you would go for the 2.1 walls, if it is closer to or 2150mm - you would go for the 2.4 walls. 
Ostrich walls have a fold over 250mm flap at the bottom which works as a 'baffle' to push water run off out and away from the walls, this baffle is also able to be buried to hold the awning stronger in stiff wind. (So the walls have a weird height system, the canvas wall section is actually 250mm lower than the walls total measurement namesake.) 
 
These walls are a game changer in wind, offering pretty good comfort improvements in icy breeze. they are also handy for keeping sideways rain off swags under the awning, 2 walls are much much better than 1 - 1 is kinda useless as wind and rain just gets around it.
