StringA-Level Contractor Kit

StringA-Level?is a set of reusable ledger boards with built-in leveling vials primarily designed for wall tile installations. A system of interlocking sections that form a continuous support shelf that is temporarily attached to the wall that tile stacks upon. Included are two types of levels; the red rigid section with a single level vial for straight wall runs and the yellow flexible section with a leveling vial on each end (possibly the world? only flexible support level) that will turn corners and conform to curves. A carrying case is included in both the 0404 Standard Set and the 1010 Contractor Set. Individual sections and replacement vials are available
