603UL Base Corner Block (Not Primed)

Baseboard Corner Blocks are used to make your baseboard installation faster and easier! The blocks are used specifically on the 90° rounded/bullnose drywall corners in your home and are made to match corresponding baseboard profiles.  The blocks save time by eliminating the extra cuts required with traditional baseboard installation, and provide a smooth transition around the corners of your walls. (made for outside corners only… not intended for square edge corners)
