These brackets can be aligned left or right, allowing for precise mounting on wall or ceiling studs to suit your space. Ideal for classrooms, boardrooms, and other large venues, the Model C with CSR delivers reliable performance, making it an excellent choice for presentations or home theater setups where a quiet, smooth screen return is essential.
