The surface-mounted L Bead is designed for use at windows, doors, and other wall termination points. It helps create a clean, finished edge in exterior wall systems.
An extra-wide surface flange allows installers to adjust and fill gaps caused by short trimming of the sheathing board. This helps ensure a precise and professional finish.
The wide flange features striations and perforations that create a strong bond between the base coat and the sheathing board.
A built-in 1/8″ (3 mm) stop helps maintain the correct base and finish coat thickness, ensuring consistent and reliable installation
Trim-tex recommends following industry-standard installation methods. All butt joints, intersections, and ends should be caulked with elastomeric sealant during installation.
