The Excellart ESP-IDS 8 Kit with IDS 2 Retainers is designed and engineered for providing a quickly assembled double rigid face aluminum sign cabinet. This Kit assembles to a 8 in. deep cabinet. It features removable retainers on all sides, providing convenient access to the inside of the sign cabinet for swift installation and removal of sign faces, power supplies, and other internally housed components. The interior placement of the retainers makes them perfect for stacking applications, and the IDS frame also provides the flexibility of mounting an internal snap-in raceway, accommodating a variety of electrical design considerations with ease.
