BTI-AKKUPOLE 50CM TUBE WHITE is an optional extension tube designed for use with the BTI-AKKUPOLE WHITE projector. This tube allows you to fine-tune the position of the projector, allowing you to achieve different installation heights. With a length of 50 cm, the tube is white in colour and can be combined with the original 1 m extension tubes, included with the projector, to achieve variable height configurations. This allows you to improve the adaptability of the projector to different installation needs.
