Plain Bearing – 40mm Deck Organiser

Designed for leading control lines and halyards along a deck or coach roof.

The cheeks are made from marine grade aluminium and anodised black.

Includes four bolts, nuts and washers.

The non-sheave column can be used as a becket.

Easily stacked to create a double-height deck organiser. When stacked the upper organiser is rated to two-thirds of the max working and breaking load.

PB stands for Plain Bearing. The sheave runs on a central stainless steel bush. Ideal for high static loads which are typical in yacht halyard systems. Plain-bearing sheaves are recommended for any system which is subject to winching.

For fast running and lower loaded lines take a look at the DB range.

We have rated the PB deck organiser range based on a 30-degree turning angle around the sheave. A 30-degree turn on a sheave will have a load factor of 50% of the line load.

Key Features:

  • Three plain bearing sheaves.
  • Lightweight and easy to install.
  • Stackable.
  • Suitable for boats up to 30ft.
  • Stylish and sleek design.

Examples Of Use:

  • Guiding halyards along a coach roof back to clutches, cleats and winches.
  • Diverting control lines around a corner under or over deck.
  • Underdeck take-up systems.
  • Redirecting a halyard, sheet or control line to have the correct lead angle into a winch or cleat.
