The Fowler 53-422-063 Precision Shaft Level is a 200 mm (7-7/8") long spirit level that has one level and one cross-test vial for determining horizontal plane simultaneously in two directions with a sensitivity of 0.1mm/m (0.001"/10") or 20 seconds. The vials are made of glass to resist scratching and provide clear readings, and the main vial can be viewed from the side and the top. A V-shaped groove in the base provides reliable seating when leveling round items such as pipes, conduit, and shafts. The level has a cast iron frame for durability. It measures 200 x 30 x 35 mm/7-7â„8 x 1-3â„16 x 1-3â„8 inches (L x H x D, where L is length, the horizontal distance from left to right; H is height, the vertical distance from the lowest to highest point; D is depth, the horizontal distance from front to back). It includes a wooden case for storage. 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 ind...
