Sportech
A 20 metre cricket lane is more than 250 square metres of netting once the roof and skirt are in.
— m²
Walls, roof and skirt, plus the joining and cutting allowance
The cage is a box: four netted walls, a netted roof or part of one, and a skirt along the foot of every wall. Dimensions, roof share, skirt, post spacing and the netting are yours; the tool has no figure for the mesh or twine a sport needs. Border rope is counted along the top and bottom of all four walls; a roof made as a separate panel needs its own edge rope too. Posts count each side at the spacing, corners shared. Doors, ball-stop curtains inside and the frame itself are not counted. **This is a netting take-off; the frame, its footings and wind load on netted walls are a structural check.**
