The Klein Tools' 69347 Plumber's Kit Replaceable Straps replace the straps in Cat. No. 69346 Plumber's Kit. The Plumber's Kit is designed to bring the benefits of the magnetic attachment of digital angles gauges to non-magnetic pipes, conduits or other objects. It consists of a metal plate and silicone straps which may be strapped to the non-magnetic object. When attached it presents a ferromagnetic surface aligned with the non-magnetic pipe to which the Digital Level with Programmable Angles (Cat. No. 935DAGL) or the Digital Angle Gauge and Level (Cat. No. 935DAG) may be attached. This item consists of two silicone straps and does not include the ferromagnetic plate.
