The AB Dublin block is an angled block available in left and right angles. There are two raised rings on the top of the block, these interlock the blocks together so adhesive is not needed.
For starting or ending walls at posts/pillars, from an existing structure or when building corners the blocks must be modified to obtain one straight edge. There are three locations where the AB Dublin blocks may be modified. These units will need to be split or cut at a quarter (1/4), half (1/2) or three quarter (3/4) length.
Splitting or Cutting Locations for the AB Dublin
Some units are produced with marks at these locations for ease of locating the cut line, but any of the AB Dublin blocks can be modified to obtain one straight edge. More for information on how to modifying blocks.
