20 ft. Braided Line + Suspension Hook: Ships with 240 in. of low-stretch braided line and a steel suspension 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.
Plumb bobs helped build the pyramids. Swanson’s brass plumb bobs are spun from solid brass for heft, tipped with hardened steel that stays sharp, and ship with 240 in. (20 ft.) of low-stretch braided line plus a steel suspension hook. Hook the line to a joist, header, or nail; drop the bob; mark the point directly below. Line coils inside the body under a threaded, removable cap for compact storage.
