DOUBLE THROUGH DECK ALLEN A2122

20mm Double Dynamic 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.

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

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
