what's the box beam level?

Box beam levels or box levels are a type of spirit level and are called such because of the shape of the level frame. If you were to cut the box level in half, you would see the aluminum is formed (extruded) in the shape of a rectangle(or box)and is generally hollow in the middle. The key to a box level's strength is its shape with four points of contact to withstand an impact. Box beam levels feature block vials, solid pieces of acrylic that are machine set into the box level frame at a high degree of accuracy. The highest level of accuracy in box beam levels is 0.5mm/m in all level positions. Only a few level manufacturers can consistency meet these accuracy standards. Box beam levels are traditionally yellow in color, so they can easily be recognized on the construction jobsite, and feature a yellow-green vial, which is also the most visible color to the human eye in a variety of light conditions.

who use the box beam level ? 

Primarily, box levels are used by framers, who will also use magnetic box beam levels in door jams. Next, finishing carpenters will use professional box beams for their accuracy. Finally, box beam levels are used in "wet" trades as a replacement for the wood level.
