The Excellart ESP-IDS 8 kit with IDS Retainers is designed and engineered for the quick assembly of a double rigid face aluminum sign cabinet. This kit assembles into an 8″ deep cabinet and features removable retainers on all sides, providing convenient access into the inside of the sign cabinet for easy 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.
