Selden Block BBB40 Double TD – S404-101-24R

The Selden BBB40 Double Through-Deck Block is a compact ball-bearing pulley designed to guide control lines cleanly through deck surfaces, bulkheads or coamings. Featuring two 40 mm ball-bearing sheaves, this block allows efficient line routing while maintaining extremely low friction under moderate and dynamic loads.

Built with glass fibre reinforced composite cheeks, stainless steel ball bearing races and stainless steel load components, the BBB40 block provides excellent durability and corrosion resistance in marine environments. The through-deck design allows lines to pass neatly through structures while maintaining smooth rope movement, making it ideal for control lines, traveller systems and other deck-mounted rigging applications.
