MARSHALLTOWN Corner Roller CR3 – 3in Corner Tool with 12in Handle for Drywall Mud & Joint Compound

Meet the MARSHALLTOWN Corner Roller CR3

Designed for corner joint compound and drywall mud, the CR3 delivers controlled coverage in tight spaces. This 3-inch roller head pairs with a 12-inch handle, giving you steady leverage whether you are working by hand or on a pole.

Why this tool is a solid choice

From the restless corners of new drywall to refinished seams, the CR3 helps you lay down a consistent coat with minimal splatter. The tool is built to be versatile for both beginners and seasoned drywall pros who value accuracy and speed.

• 3-inch roller head provides precise application at corner joints and seam lines.
• 12-inch handle offers a comfortable grip and extended reach to reduce arm fatigue.
• Two sizes are available (3-inch or 5-inch) to fit different tasks and preferences.
• Use it as a hand tool with the included handle or attach to a 1-inch threaded pole with the adapter.
• Replaceable acrylic cover can be swapped for a lambs wool texture for different finishes.

Practical usage notes: this tool is designed for spreading drywall mud and joint compound, not for priming or painting. It shines when you need clean lines along corners, around window frames, and where walls meet ceilings. While results depend on technique and material, many builders appreciate the control the CR3 offers in challenging rooms.

How it fits into your workflow

• Prep afterward with light sanding for a smooth surface before paint or texture.
• Keep spare covers on hand — acrylic and lambs wool options are available separately.

In short, the MARSHALLTOWN Corner Roller CR3 is a compact, adaptable drywall tool that can help you tackle corner joints and mud applications with confidence. Consider it a flexible companion for both small touch-ups and larger installations.
