Wood Blocks

Wood Blocks

Wood Blocks for Manila Rope.

Traditional blocks.

The wood is providing protection from damage to the ship and block, not strength.  The strength is provided by a steel frame inside the wood.

Wood blocks come in 3 sizes; Single, Double or Triple.

This refers to the number of sheaves and therefore the amount of mechanical advantage provided by the block.

Wood Blocks are available with 3 types of fittings; Hook, Swivel or Upset Shackle.  Please specify which when placing your order.

While traditionally a wood block for manila rope is used with manila rope, it's now often used with any synthetic fiber rope.

These can be used with many types of synthetic rope as long as load limits are respected.

This type of block should NOT be used with wire rope.
