The base of the levels features a groove running the length of the base, which provides a reliable seat for round work such as pipes or shafting
Cross test vial enables simultaneous leveling in two directions
The vials are adjustable to a positive setting and are housed in a satin finished brass tube with a friction-fit closing cover to prevent breakage
Main level vials have graduations that are approximately 80-90 seconds or 0.005 in per foot (0.42 mm per meter)

The vial is made of ground glass to resist scratching
Levels are instruments that are used to determine the true horizontal or vertical plane of a surface
The most common type of level is the spirit level, or bubble level
Spirit levels have a liquid-filled, bowed tube (also called a vial) with a bubble that moves when slight adjustments are made to the level
When the bubble settles between marked points on the vial, it indicates that a surface is horizontally or vertically straight
Levels can have one or more vials to determine the horizontal plane, the vertical plane, or various points between, such as a 45 deg angle, simultaneously
Some levels include a laser line indicator that projects a horizontal or vertical beam on a surface
Bulls eye levels, or surface levels, are circular, flat-bottomed spirit levels that determine whether a surface plane is level
Machinists' levels are made of metal and have surfaces designed specifically for rugged use in a machine shop or tool room
Levels can range from highly-complex and accurate machines, such as those used in the surveying and construction industry, to precision instruments used in carpentry and other building trades, to simple, pocket-sized devices for do-it-yourself project
