AB York Block
The AB York block is a tapered block, with a long and a short side. Creating curves with this shape is simple, and for straight walls, just rotate every other block.
Splitting or Cutting Locations for the AB York
AB York blocks are split in half down the center of the raised ring when modifying. Some units are produced with marks at this location for ease of locating the cut line but any of the AB York units can be modified at these locations to obtain one straight edge.
Note: The AB Dublin and AB York can be installed upside down when the opposite angle is needed during construction. This should typically only be done on the top course.
