30mm Dynamic Ball Bearing High Load Through deck double allenite block.
Allen's 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 sheaves in the through deck block are plain bearing. This allows high loads to be put through the sheaves without the risk of failure to the bearing system. Ideal for leading rigging wire through a surface.
Sheaves – Stainless steel sheaves allow this product to work more efficiently with wire and give a better durability.
