Customer review summary
Really helpful in handling a small, local order for sprial duct components. I had been ordering parts online, but was pleased to discover Spiral Manufacturing Co Inc.
I needed a few pieces for my dust collection setup. Even though I only ordered a few things, they treated me like a regular customer. Highly recommend and will be back again if I need more!
Not bad, but they have only 1 dock and a little bit tight, so slow down when u approach to the warehouse.
