Solid Brass Body: The heavy, corrosion-resistant brass construction provides enough weight to settle quickly and resist swaying in light breezes.
Replaceable Hardened Steel Tip: The sharp point is made of hardened steel to withstand repeated contact with concrete or stone. It is fully replaceable if it eventually dulls or breaks.
Bonus Spare Tip Included: Most 47-973 kits come with an extra steel tip stored in the package, ensuring you don’t have down-time on the job site
Screw-Top String Attachment: The top cap unscrews, allowing you to feed the string through the center hole. This ensures the weight is perfectly balanced and the string is aligned exactly with the tip.
Polished Lacquer Finish: The brass is coated with a clear lacquer to prevent tarnishing and oxidation, keeping the tool easy to clean and professional-looking.
Thru-Hole for Tightening: A small hole in the body allows you to use a nail or small screwdriver as a lever to tighten the screw-top or loosen a stuck tip.
Aerodynamic Profile: The slim, tapered “torpedo” shape is designed to minimize air resistance, helping the bob reach a stationary state faster.
The 47-973 is a precision gravity tool machined from solid brass. It is designed for contractors who need to establish a perfectly vertical (plumb) line for framing walls, installing elevator shafts, or setting deck posts. Its brass construction is preferred by professionals because it is non-magnetic, meaning it won’t be attracted to steel studs or nearby machinery, which would ruin the accuracy of the reading.
