How many boxes of nails do I need for installation?

I bought a 15x9 piece of turf, will 1 box be enough?

A box of nails has about 800-1000 pieces in it, weights about 50 lbs.. You will have more than enough for your size of artificial grass installation. Unfortunately, the nails only come in as 50 lb box, you will have to get a full box for your installation with some leftovers.
