Apex S590N Plumb Bob Stainless Steel 7.3 Inch

Product Description

The APEX S590N is a cylindrical plumb bob machined from stainless steel, designed to establish a true vertical reference point on layout and positioning work. At 7.3 inches in overall length and 1.3 inches in overall width, this bob carries meaningful mass for stable hanging and accurate plumb transfer. The stainless steel construction resists corrosion and surface wear, making it suited for repeated use in field and shop environments. It ships without graduation markings, which keeps it appropriate for oil gauging and general plumb-line applications where markings would interfere with the work. Installers in plumbing, construction layout, and mechanical trades reach for this tool when a reliable, unmarked plumb reference is needed.

The S590N fits into plumb-line setups used during pipe rough-in, structural layout, and equipment alignment in both residential and commercial jobsites. Its oil gauging designation makes it a standard choice for tank depth measurement applications where a clean, smooth stainless surface is required. The cylindrical shape allows it to pass through tight openings and hang freely without rotation bias. No special thread or line is included; the bob accepts standard plumb-line cord or braided string through its top fitting.

Key Features

• Stainless steel construction resists corrosion and surface pitting on working surfaces
• Cylindrical profile hangs without rotation bias and passes through narrow openings
• No markings on body, suitable for oil gauging and clean plumb-line transfer work
• 7.3-inch overall length provides substantial mass for stable vertical hang
• Compact 1.3-inch width fits standard plumb-line access points

Compatibility

Designed as a standard unmarked plumb bob for general layout, plumbing rough-in, and oil gauging applications where a cylindrical stainless steel bob is specified.

Installation Notes

Plumb bobs are a hand-measurement tool; no power source or power disconnection is required before use. Attach to a quality braided or twisted plumb-line cord rated for the bob weight before suspending. Allow the bob to come to a complete stop before marking the plumb point, and shield from air drafts that can introduce lateral error. Store the bob in a dry location to preserve the stainless finish and thread fitting.
