Vinyl Corner Bead

A vinyl corner bead is a rigid, plastic L-shaped strip used in drywall finishing to protect and reinforce outside wall corners, providing a straight, durable edge for a clean finish, especially useful for curves, arches, or areas needing dent resistance, as it won't rust or dent like metal beads and offers flexibility for movement. It's installed with adhesive or staples, allowing mud to bond through perforations for a seamless look, making it popular for achieving smooth, damage-resistant corners.
