A left-right ruler, also known as a reversible ruler or double-sided ruler, is a measuring tool that features markings on both sides of the ruler, allowing it to be used for measuring in either direction. This makes it a convenient tool for measuring from both the left and right sides of an object, without the need to flip the ruler over.
Lance Left-right rulers are made of aluminum and have markings in inches or metric units on both sides of the ruler. They may come in a variety of lengths, but the most common sizes are 12 inches or 30 centimeters.
Lance left-right rulers are commonly used in a variety of settings, such as in schools, offices, and workshops, and are especially useful for measuring in tight or hard-to-reach spaces where flipping the ruler over may be difficult or impractical. They can be used for a wide range of applications, from measuring the length of a piece of fabric to measuring the distance between two points on a wall or piece of furniture.
To use a left-right ruler, you would simply place the ruler along the object or distance you want to measure, and read the measurement from the markings on the side of the ruler that is facing you.
Overall, left-right rulers are a simple but versatile tool for anyone who needs to measure length or distance in both directions. They are easy to use, accurate, and can be used for a wide range of applications in various settings.
