Mudmaster Accessory - Drywall Tools

Shown left is is the filler extension for use when wearing stilts. The dry wall accessory saves dismounting stilts to reload drywall tools.

The gray device at the top left, with a yellow cord, is the control that activates the pump for loading. It is the Remote Control and comes with the Mudmaster, so it is NOT an additional purchase. This is the same remote that is used to fill auto-tapers.

No stooping... No precarious balancing with bending over...

Save time and your back.
