20 ft. Braided Line + Suspension Hook
Ships with 240 in. of low-stretch braided line and a steel S-hook at the anchor end. Hook the line to a joist, a header, or a nail; drop the bob; mark the point directly below without tying a knot or dressing a fresh line every setup. Line coils inside the body under the removable cap for compact storage.
Solid Spun Brass
Spun from solid brass for full 8 oz. heft. Won’t dent on a concrete pour or a roof deck the way a cast-zinc bob will.
Removable Top, Centered String
Threaded brass cap unscrews so the string anchors at the body’s centerline, not at the cap. A centered string reads true plumb every time.
Hardened Steel Tip
Hardened steel point reads the mark cleanly on softwood, hardwood, and concrete. Brass tips go dull after years of use; this one stays sharp.
