Kraft Tool BL350-5PR 4″ Wood Line Blocks (5 Pairs)

Create an even brick or block course with line blocks. Secure the 4″ hardwood block on the outside corners of your masonry project with the line knotted to hold it in place. The 1-1/4″ square block grips tightly to the corners for straight lines. Run the line through the channels on the block to eliminate obstructions and protect the line for wearing down. Retighten the line as you move it up your wall to create a straight row with each new course. Use with Kraft Tool Co.® or W. Rose Mason’s Line for superior results as you create an even brick line. Package of 5 pairs.
