DIY Frequently Asked Questions / Carpenter’s Level')">
Tool that employs bubble vials positioned in the center and both ends to check vertical and horizontal surfaces for level or plumb.
Made of either hardwood with brass binding, metal (aluminum, magnesium) or high-impact plastic.
Typically 24″ to 48″ long, but some models (generally mason’s levels) are longer and can be up to 72” in length.
Some models include split level or graduated vials that have two sets of lines, with the outside line representing a 2 percent grade that conforms to the slope required for gutters and waste lines to drain properly.
Some models include electronic features to calculate angles on sloped surfaces (roof pitches, stair slopes and drainage angles) and display reading in degrees, percent slope or inches per feet (rise/run).
