Through Deck Block Range Expands 

We are pleased to announce that our range of 20mm & 30mm through deck blocks is expanding to include stainless steel sheaves and recycled acetal sheaves. 

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. Available with one or two sheaves and in plain and ball bearing systems to suit a wide variety of applications.
