Don’t order from Lowe’s if you’re on a schedule.

Would Not Recommend

I should have learned my lesson the last time - I had a delivery date and it was nearly 3 weeks later before it arrived. I have now gotten my second delay on this product. We are at a standstill in our project because they can’t deliver when they said they will. Had they been upfront and honest I would never have ordered. I could have driven to pick it up much faster. Very discouraging. 0 stars.
