The Inside/Outside Corner Expansion Joint is designed to create a clean, plastered corner while allowing movement between two 90 °- connected walls.
This joint helps prevent cracking caused by building movement or expansion. It absorbs stress at both inside and outside corners, protecting the finish over time.
The result is a smooth, professional look and long-lasting durability. It is the ideal solution for projects that require a clean finish with built-in flexibility.
