The projection of the canopy is the distance from the wall to the front of the canopy. The Homestyle Multi Purpose Canopy is available in 5 different projections: 1.5m, 2.5m, 3.0m, 3.5m, 4.0m. The projection stated for these canopies is panel length when laid flat, the actual projection will be slightly less when you add pitch to the roof – please see the detailed drawings for the size you are looking for. Remember we can produce a canopy to suit most size requirements so if you do not see the kit you need please contact us and provide us with your exact requirements.
