The Excellart ESP SF Standard Frame, crafted from domestically sourced 6063-T6 architectural-grade aluminum, serves as a single-face sign frame extrusion designed for constructing aluminum sign cabinets. This frame offers straightforward assembly and a wide range of design options. While it does not have built-in retainers, it is compatible with multiple retainers—including LF, F, FF, FF2, and XW retainers—to achieve the desired depth.
