The Customer Service Rep was great. He had all the information off the top of his head. one of my questions was (With the materials shortage (Screws) would they be able to fill the order? The CS Rep assured me that the company has tons of screws in stock and would easily fill this order. The leed time on the website was 7-10 days. I believe it was exactly the ten days. the screws arrived in a timely manner.
Thank you for the assistance and the screws.
