Through Deck Blocks - Allen

Allen 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.
