The Palram-Canopia Aquila 2050 siding kit provides a flat surface for mounting Aquila 2050 and Aquila 4100 door awnings on lap siding and for anchoring the awnings to wall studs. The dark aluminum powder-coated mounting plate is durable, rust-resistant, and maintenance-free. One siding kit is needed for Aquila 2050 awnings and two are needed for Aquila 4100 awnings. This is the siding kit only. Awning sold separately.
