Selden Block BBB40 Single / Becket Swivel – S404-101-03R

The Selden BBB40 Single Becket Swivel Block is a compact ball-bearing pulley designed for smooth rope handling in light to medium-duty marine rigging systems. Featuring a 40 mm ball-bearing sheave, integrated becket and swivel attachment, this block allows a control line to be securely dead-ended while the swivel head enables the block to align naturally with the direction of load.

Constructed with glass fibre reinforced composite cheeks, stainless steel ball bearing races and stainless steel load components, the BBB40 block delivers extremely low friction and dependable durability in demanding marine environments. It is commonly used in traveller systems, control lines, reefing lines and other dynamic sailing applications where smooth rope movement and reliable performance are required.
