Lufkin TT590N Brass Plumb Bob 20 Oz 6.75 X 1 Inch

Product Description

The LUFKIN TT590N is a solid brass plumb bob designed for accurate vertical reference work on construction, plumbing, and electrical layout jobs. Weighing 20 ounces and measuring 6.75 inches in length with a 1-inch diameter, this bob provides the heft needed for steady plumb lines in field conditions. The body, tip, and point are all brass construction, delivering corrosion resistance and long-term durability. It is a standard tool for plumbers, electricians, carpenters, and general contractors who need reliable gravity-referenced alignment during rough-in or finish work.

The TT590N is suited for residential and light commercial applications where a plumb reference is needed to locate anchor points, verify vertical alignment of pipes or conduit, or transfer layout marks from floor to ceiling. It performs well in both interior framing stages and finished-space environments. The non-replaceable brass tip is integral to the body, keeping the tool simple and consistent over repeated use.

Key Features

• All-brass construction including body, tip, and point for corrosion resistance
• 20-ounce weight provides stable hang and minimal swing in typical job-site conditions
• 6.75-inch length with 1-inch diameter for a balanced, easy-to-handle profile

Compatibility

Installation Notes

Attach the TT590N to a suitable plumb-bob line or string tied through the top suspension point. Allow the bob to hang freely and come to a complete stop before marking a reference point. Keep the work area free of air drafts that could deflect the line during use. No power tools or fasteners are required for normal operation.
