Stanley 47-973 Plumb Bob 8 Oz Brass

Product Description

The STANLEY 47-973 is a solid brass plumb bob used to establish true vertical reference lines on jobsites and in construction applications. Weighing 8 ounces, this plumb bob provides the mass needed for a stable, accurate hang in both interior and exterior conditions. The brass construction resists corrosion and holds up to repeated use in demanding trade environments. It is a standard hand tool used by carpenters, masons, plumbers, electricians, and general contractors whenever a reliable vertical reference is required.

This plumb bob is suited for residential and light commercial construction tasks including layout work, wall framing, column alignment, and utility rough-in positioning. It is used wherever a worker needs to transfer a point directly downward to a floor, footing, or layout mark. The 8 oz weight class is a common choice for moderate-height drops where a lighter bob would swing excessively and a heavier one would be unnecessary.

Key Features

• Solid brass construction resists corrosion and provides consistent weight distribution
• 8 oz weight delivers stable hang with minimal sway for accurate vertical transfer
• Standard plumb bob geometry with a precision-ground tip for pinpoint accuracy
• Durable material suitable for repeated use in field conditions

Compatibility

Designed as a standard replacement or additional plumb bob for use with common chalk line reels and string setups in general construction and trade applications.

Installation Notes

A licensed or journeyman-level tradesperson in carpentry, masonry, or plumbing typically uses a plumb bob as part of layout work before structural or rough-in installation begins. Secure the string to a fixed overhead point and allow the bob to hang freely until it stops swinging before marking the reference point below. Keep the tip away from surfaces that could deflect its hang. No power tools or shutoffs are required for use.
