Abstract
A drywall mud applicator wheelless control tube is provided. The drywall mud applicator wheelless control tube has a plastic component (in an embodiment) having a rubber o-ring or spring which provides pressure to a slanted cylindrical ledge protrusion which allows the control tube to slide up and down a main mud applicator tube without the need for wheels on the control tube. As a result, the wheelless control tube increases the sliding and smoothness of the control tube as it slides over the main mud applicator tube.
