Plumb Bobs

A plumb-bob or a plummet is a weight, usually with a pointed tip on the bottom, that is suspended from a string and used as a vertical reference line, or plumb-line. It is essentially the vertical equivalent of a “water level”.

The PTA plumb bob is manufactured from corrosion resistant, chrome plated steel with removable brass cap for easy and accurate string installation. Weight is 8 oz.
