About this file
This technical specification drawing is for a Daktronics LED display system measuring 17.07' x 30.19' (13x23 modules) with a flat border design. The display features RGB LED color capability, all-aluminum construction with front and rear accessibility, and ships in two sections requiring on-site assembly. Key specifications include an active display area of 514.943 square feet, matrix size options of 520 x 920 pixels (10SMD) or 312 x 552 pixels (16MT), total weight of 5,325 pounds split between Section 100 (2,902 lbs) and Section 200 (2,423 lbs), and structural ratings supporting wind pressures up to 72 PSF with specific mount spacing requirements.
Installation requirements specify that the customer is responsible for designing and certifying the support structure, obtaining local certification for steel mounting, and providing appropriate lifting equipment with safety factors, while sections cannot be lifted in wind speeds above crane capacity or OSHA's 20 MPH limit. The display includes rear intake and exhaust ventilation systems requiring 19.333 square feet of open area for natural convection or 5,800 CFM forced ventilation if natural convection cannot be achieved. Power ratings are referenced in a separate drawing (5280640), and multiple mounting options are available including rocker with/without ledger beam mounts, offset rocker beam mounts, T-clip stringer mounts, and lug mounts, with detailed drawings provided for each mounting method.
