Product Features


  • • These levels have ground and graduated main vials
    • These 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
    • 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
    • Main level vials have graduations that are approximately 80-90 seconds or 0.005 in per foot (0.42 mm per meter)
    • Cast iron base for durability
    • There are five, six, or seven lines on each side of the bubble, depending on the base length
    • Unmilled surface
    • Brass frame material
    • V-shaped groove along the base provides reliable seating when leveling round items
    • 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
