MARSHALLTOWN Corner Roller CR3 – 3in Roller with 12in Handle for Drywall Mud & Corner Joints

Meet the MARSHALLTOWN Corner Roller CR3

The MARSHALLTOWN Corner Roller CR3 is crafted to help you apply drywall joint compound and mud with precision around interior corners.

This tool is designed to simplify corner work while delivering consistent coverage, making it a practical addition to any drywall kit.

• Two sizes available—3" or 5"—to suit different joint widths
• Acrylic cover is replaceable; lambs wool texture option available; replacement covers sold separately
• Converts to a pole tool by attaching to a 1-inch threaded handle with the included adapter
• Intended for spreading drywall mud and joint compound, not as a painting tool

Two ways to use it

• Use by hand for precise control in tight corners and along edge lines

Texture options and maintenance

Switch between acrylic and lambs wool covers to suit your texture preference or project needs. Replacement covers are available, so you can customize the finish while keeping cleanup simple. When not in use, follow standard cleaning steps for mud tools to extend the life of the cover and the mechanism.

Usage note: While this tool excels at applying joint compound and mud, it is not designed as a general painting tool. Pair it with the right accessories and you can achieve smoother corners and more consistent mud distribution without compromising technique.
