This projector interface is equipped with fine-tuning for precise alignment with the projection surface. Once aligned, the projector remains in its position. By turning the unique friction ring, any play in the interface connections is eliminated, making the mount a solid and very stable solution. The height-adjustable projector ceiling mount kits can be used when the ceiling height is unknown or when flexibility is desired. These mounts are available in three lengths, allowing for variable height adjustment. The Cable Inlay System runs the entire length of the pole and even allows for cable management after installation. It provides ample space for all necessary cables and enables you to hide all cables in seconds.
