Twin Wall Narrow Boat Deck Plate Adapter 5" MB

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

This narrowboat deck plate is a high-quality component designed for use where a twin wall insulated flue system passes safely through the deck of a narrowboat. It provides a secure, neat, and professional solution for deck penetrations, making it ideal for stove and appliance installations where a traditional masonry chimney is not available.

Designed with both performance and ease of installation in mind, this deck plate helps create a tidy finish while maintaining safe clearances to surrounding materials. Its durable construction and matt black powder-coated finish allow it to blend seamlessly with our black twin wall flue systems, offering both long-lasting reliability and a smart, modern appearance.

Twin wall insulated flue systems are widely used in narrowboat installations because their insulated design helps reduce heat transfer and allows for safe passage through structures such as decks and roofs.

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.
