Stabila's 3-Piece PRO SET-80 AS Spirit Aluminum Box-Beam Levels w/ Carrying Case is built for accurate horizontal and vertical measurements across a range of common construction tasks. The box-beam profile provides a stable reference surface, while precision-machined edges support consistent positioning against work surfaces. Multiple level lengths allow users to select an appropriately sized tool instead of relying on a single level for every application. The included carrying case also helps protect the levels between jobs while keeping the set organized for professional tradespeople, installers, remodelers, and DIY users.
