Built from tough alloy construction, this holder includes both the clamp and the 18-inch notched steel rod. The clamp adjusts fully up and down on any 3\/4-inch diameter stake, allowing precise height positioning without tools. The notched rod captures and holds the string line securely in place. It is used primarily by concrete finishers, flatwork crews, and general contractors laying out slabs, footings, or curbs.\u003c\/p\u003e\n\u003cp\u003eThis holder is suited for residential and commercial concrete forming applications where accurate string line placement is critical to achieving proper grade and alignment. The adjustable clamp design makes it a practical fit for standard 3\/4-inch diameter form stakes commonly used in slab and footing layouts. Note that string line and steel stake are not included with this holder. Replacement components are available separately: bon clamp 22-989 and bon rod 22-991.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes both the clamp and 18-inch notched steel rod as a complete assembly\u003c\/li\u003e\n  \u003cli\u003eClamp adjusts fully up and down on any 3\/4-inch diameter stake for flexible height setting\u003c\/li\u003e\n  \u003cli\u003e18-inch steel rod is notched to securely retain the string line during layout\u003c\/li\u003e\n  \u003cli\u003eTough alloy construction designed for long wear on the jobsite\u003c\/li\u003e\n  \u003cli\u003eReplacement parts available separately (clamp 22-989, rod 22-991)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit any standard 3\/4-inch diameter concrete form stake.
