The 10 inch adjustable SB1000 Plaster Finishing Mud Box allows you to apply the first coat of joint compound to embed tape at butt joints and flatten joints on walls and ceilings of up to 3 m height.

The adjustable crown setting dial allows the user to easily adjust the amount of joint compound applied over the tape on the drywall joint.

This is very helpful when progressing from the first embedding application to the second or third finishing coat.

The pivoting axle helps to compensate when the drywall or sheetrock on one side of the joint is higher than the other side of the joint.
