Plumb Bobs

Plumb Bobs

Plumb bobs are integrated with a pointed tip, on the bottom surface, to act as a plumb-line or vertical reference line in construction and surveying jobs. Raptor Supplies offers a wide range of these plumb bobs from brands like Johnson, Lufkin and Stanley. They are used with a variety of instruments (including levels, theodolites, and steel tapes) to position it exactly over a fixed survey marker or to transcribe positions, on the ground, for placing a marker. They are available in brass, clear lacquer, nickel-plated and polished clear lacquer finish options on Raptor Supplies.
