Twin Wall Narrow Boat Deck Cap 5 Inch MB

Please note: The diameter advertised refers to the internal measurement of the flue, not the external measurement.

This narrowboat deck cap is a high-quality accessory designed to be used when a twin wall insulated flue system is not in operation. It provides a simple and effective solution for temporarily sealing the flue opening, making it ideal for use during warmer months when the stove is not in use, or when navigating under low bridges.

Designed with practicality and durability in mind, the deck cap helps prevent rain, debris, and downdraughts from entering the flue system when it is not in use. It also offers a neat and professional finish to the deck when the flue has been removed.

Finished in a durable matt black powder coating, the deck cap integrates seamlessly with our black twin wall flue systems, maintaining a clean and consistent appearance across your installation.

We are so confident in the quality of our twin wall chimney system that it is backed by a 30-year no-quibble warranty and customer satisfaction guarantee.
