20mm Single High Load Through Deck Block.

Our through deck blocks offer frictionless guidance for rope and wire control lines which are required to pass through a deck.

Featuring a hard-wearing acetal body shaped perfectly to house the sheave, which results in a performance that you can rely on for adjustable rigging and other highly loaded applications.

Bearings – The sheave in this through deck block are plain bearing. This allows high loads to be put through the sheave without the risk of failure to the bearing system. Ideal for leading rigging wire through a surface.

Sheaves – A stainless steel sheave allows this product to work more efficiently with wire and gives better durability.
