Measure hands-free without permanently mounting a ruler. These rulers have a magnetic back, so they cling to most surfaces.

Always have the size you need on hand—these sets come with rulers in three different lengths. Their back is magnetic, so they cling to most metallic surfaces for hands-free measurements without mounting a permanent ruler.

For repeated height and depth measurements, stick these rulers to walls, tanks, and other vertical surfaces. Their numbers are printed from bottom to top or top to bottom, so you don't have to tilt your head to read them. Since these rulers permanently adhere to surfaces, they free up your hands as you work—no more lining up rulers or tape measures.

Take division out of the equation when building half-scale models and prototypes. The distance between the graduations on these rulers is half the printed measurement—just use your object's true dimensions to get a model half its size. Stick these rulers to your bench top for a permanent, hands-free measuring guide.
