Selden PBB16 Single Block – 16 mm Plain Bearing Block for Light Lines

The Selden PBB16 Single Block (401-001-01) is a compact and lightweight plain bearing block designed for light-load applications on board. Its simple fixed head construction makes it a practical and reliable solution for small line handling tasks.

This block is specifically developed for low-load systems such as flag halyards, lazy jacks, and other lightweight control lines. The plain bearing design ensures consistent operation with minimal maintenance, making it suitable for static or lightly loaded setups.

The sheave is made from durable composite/acetal material, while the cheeks are reinforced for strength and to prevent line jamming. The stainless strap provides a secure attachment point for lashing or fixed installation.
