Selden Block BBB40 Single TD – S404-101-22R

The Selden BBB40 Single Through-Deck Block is a compact ball-bearing pulley designed to guide control lines cleanly through deck surfaces, bulkheads or structural panels in marine rigging systems. Featuring a 40 mm ball-bearing sheave and through-deck mounting design, this block allows efficient line routing while maintaining extremely low friction under moderate and dynamic loads.

Constructed with glass fibre reinforced composite cheeks, stainless steel ball bearing races and stainless steel load components, the BBB40 block delivers excellent durability and corrosion resistance in demanding marine environments. The through-deck configuration allows control 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.
