AirDrain Agronomic Natural Grass Drainage at Chesapeake Energy Roof Top Sports Field
Typically when installing a large area, staging the grid into parts of 3 is best.
Pull the 3 part grid to make sure the they are attached well.
attach the small end first to the row, holding the left side up so it doesn't snag, snap in.
That should line up the left side to attach, once all male connectors are lined pull all 3 away from the left side to snap in and you should be done.
Be aware of the yellow connectors on one corner of each part, if the male connectors are not dropping into the female connectors some thing is wrong.
You should be able to do 21 sqft. once staged atleast every 20 seconds.
