What is a straight edge?
A Straight Edge can be used to draw out a straight line or to ensure that a surface is flat, but it cannot be used to measure length. The tool has an edge that is free from curves and is most effective at transcribing lines as well as determining their straightness. A ruler on the other hand can be used to draw a straight line, check for flatness, and measure length. A ruler is typically measures in inches and centimeters to give a more accurate and precise measurement. Rulers can also be used to measure distances. Rulers and straightedges alike can be made from a variety of materials from metal, to wood, and even plastic. HomElectrical has a large selection of both straightedges and rulers to meet the needs of any project.
