I have a small shop so equipment mobility is a must. So, when I purchased a lightly used Grizzly table saw, I immediately purchased the mobile base and extension kit. But that is just half of the story. During shipment, the box carrying my original order was severely damaged and all of the hardware was lost. I contacted Grizzly Customer Service and explained my dilemma the problem. Without hesitating, Grizzly quick shipped every nut & bolt I needed to assemble the product. Job well done.
