Designed to blend in and work with almost any environment, the AEC adjustable column features the ability to extend drop lengths from 6 inches to 12 feet. Whether it's for the home cinema, an office or mounted from a tall cathedral ceiling, the adjustable column supports up to 900lb, making it ideal for home, exhibit, retail or digital signage applications. The new slot design makes for easy incremental height adjustments to find the perfect position and then securely locking it into place. The AEC column's cylinder shape conveniently offers ample internal space for cable management of multiple cords, ultimately giving a clean look to any installation.
