Some of a mason's tools are designed for laying units: the trowel, brick hammer, jointers, and chisels. Other tools, such as the level, rule, and masons line, are used only for plumbing, leveling, and layout. These tools ensure good quality and alignment. Any time spent with the alignment tools shortens the time spent with production tools. The result: less job production. If a mason could align masonry units without a level, he could cut the time it takes to build a lead in half. Using a corner pole can accomplish this. Corner poles are posts that are braced or fastened in a plumb position at the ends of a masonry wall. The line is stretched between the poles. Once a course is laid, the mason slides the line up the poles to the marking for the next course of masonry. Corner poles can increase overall production by 10% to 25%. What features should you look for in corner poles? They should be lightweight, sturdy, noncorrosive, and have few working parts. The poles should be fast and easy to erect and adaptable to veneer and solid masonry, with attachments for backup masonry, quoin corners, and chimneys.
