The COUNTERTOP Cart allows you to safely and easily move large shapes, whether finished items, or unfinished materials, around the shop. You can also use it when transporting such items from your shop to your truck, and from the truck to the job site. The sides are designed to provide enough open area to allow for sinks or other protrusions. Each 6" material support is sheathed with PVC tubing to help hold the material on the cart and protect the things you make and move. Rolls easily on 2 swiveling and 2 fixed 6" casters.
