I had to reorder hinges (I wasn’t happy about that), however once I figured out the solution (luckily everything was in stock), the team went above and beyond to get my shipment out SAME DAY and overnight the needed parts to my job-site. Everything arrive

I attempted to reach the Haas cabinet company, as I have done in the past, from drawer replacement parts. I could not reach them. I found this company on line and appreciated the personalized help from them. She walked thru the entire measurement process
