Kapro 105 Topgrade 24" Box Level Slope Vials Precision Measured Milled Aluminum

The Kapro 105 series gradient level is a box-style spirit level with solid acrylic vials?one plumb and three or five gradient?for determining vertical plane as well as slope from 0% to 2% with a sensitivity of 0.5 mm/m (0.0005"/inch) for precise readings. Each gradient vial is calibrated to a different slope. These vials are machined from an optical-grade acrylic block to provide clear readings and are shockproof to resist breakage. The body is made of aluminum for light weight and corrosion resistance, has a milled leveling surface for accuracy, and has end caps that help absorb impacts. The level is available in a 24" length that has three gradient vials and a 48" length that has five gradient vials. Levels are used in the building trades, engineering, surveying, and metalworking, among other applications. 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-degree angle, simultaneously. Some levels include a laser line indicator that projects a horizontal or vertical beam on a surface. Bullseye 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 projects. Kapro manufactures spirit levels, laser levels, layout tools, and measuring tools. The company, founded in Israel in 1974, meets International Organization of Standardization (ISO) standards 9001, 14001, and SA8000.
