    ### Black Nylon Ball Day Shape — 350mm

Assemble a black ball day shape from this item’s two slot-together nylon sections. The pack makes one complete 350mm-diameter signal, which separates for flat storage. Display lines and other attachment equipment are not expressly included.

### About this product

The intersecting sections create the ball-shaped appearance for visual daytime signalling. Once separated, they lie flat for storage with the vessel’s other day-shape equipment.

Assembly and display follow the product instructions and the relevant signalling reference. The physical shape does not determine what a particular vessel must display or the meaning of every combined signal.

Use an authoritative navigation or operating reference for its intended application. The stated diameter is a physical size, not a guaranteed recognition distance.
