These exterior wall covers are ideal for applications where concealment is desired, high wind loads are expected, or lateral shear is required. All XLP systems have a standard aluminum infill panel, which can be color-matched to blend with adjacent finishes. XLP joint sizes range from 25" to 34". This system has a structural ladder frame assembly utilizing two heavy-duty magnetic closures and a pulley system returning the cover to the nominal position after a seismic event. Contact the factory for larger sizes or custom applications.
