Starrett Solid Brass Corrosion - Resistant Plumb Bob with 10 Feet Nylon Cord and Replaceable, Hardened Steels for Reliable Accuracy - 8oz. Weight - PBB-8

Easy to set up. Well made. Not from China.

Mine came in a blister pack that was sloppily taped together. It had been dropped enough that the point of the bob had punched a hole in the bottom of the plastic packaging and damaged the included string. Luckily the tip was intact or I would return it.It's ridiculous buying a high quality tool that's packaged so cheaply. Do better Starrett.
