Navigation sign RB-4-01

Floating navigational sign of the 4th type size of triangular silhouette is intended for navigators' orientation on inland waterways: it marks the edge of a ship's course, turns of straight sections of a ship's course. The triangular silhouette buoy marks the left edge of the ship's course. The buoy is a welded polymer product with a sealed compartment filled with foam material with low water absorption, which ensures unsinkability of the product. The case is made of impact-resistant, frost-resistant plastic (block copolymer), providing high resistance to mechanical damage, maintainability and durability of the product.
