HCL1 is a concealed in-ceiling mount electric screen, where the casing is mounted within the ceiling structure, creating a flush surface. The screen surface is flat, with exceptional color and uniformity. This screen is perfect for any residential, commercial or house of worship installation(including business meetings boardrooms classrooms and home theater setups) that requires a flushmounted projection screen that can be hidden while not in use. HCL1 features the IR remote, 12V trigger and RS485. The white case is made of aluminum. Its unusually quiet operation is due to the powerful and quiet tubular motor.
