I have 50 piece's measuring approximately 71” each. This translates to approximately 25’ of boards. I removed them from my front porch. There are a couple of pieces that have cutouts where my columns were. Each board does have screw holes on either end. You lose 5” if you cut them off, the boards would be 66” each at that point.
These boards are still available at Lowe’s if you need more. This is a great opportunity to start a project for much less than starting from scratch!
