How many bender stakes do I need for 15x16 S blade 50?

It will depend on the length of edges of your artificial grass installation. If you have all the sides exposed that need to use bender boards to finish off and your area is a perfect 15’x16’, you will have 62’ of bender boards, and typically you will need a stake every 4-6’, so 10 to 12 pieces will be sufficient for your project.
