Great for









Marquee-Lok can be used as a soffit and fascia panel, and also has the added capability to be used as a wall panel.

Beauty is the Simplicity of Design 
Marquee-Lok panels are 12" wide and 1" high.  The end effects are a smooth, unbroken plane or a subtle ribbed appearance.  Panels are manufactured "cut to length," eliminating the need for field cutting.

Unique locking design 
McElroy Metal's Marquee-Lok panels feature a unique locking design that adds strength and helps to prevent the panels from unlatching due to high suction force during a wind incident. No other panel in the industry features this type of locking mechanism.

To meet ventilation requirements, Marquee-Lok panels are available vented. Control the degree of airflow by utilizing all vented panels or a mix with non-vented panels.
