Get Perfectly Vertical Lines Every Time with Plumb Bobs
A plumb bob is a timeless tool used to achieve true vertical alignment. Whether you're building a deck, installing wall frames, or laying foundations, these weighted tools ensure precise results every time.
We offer a variety of steel and brass plumb bobs in weights ranging from 8 oz to 32 oz. Our selection includes trusted Australian brands like Supercraft and Stanley FatMax, known for their durability and accuracy. Choose from hexagonal or cylindrical designs, each featuring a pointed tip for precise marking. Many models include replaceable tips and protective storage cases or leather sheaths.
The right weight depends on your project. Lighter 8-12 oz models are ideal for indoor carpentry and general tasks, while heavier 16-32 oz options are better for outdoor use or tall structures where wind may be a factor. Brass plumb bobs are non-magnetic and rust-resistant, making them perfect for long-term use. Steel models offer excellent value and durability for everyday projects.
Most plumb bobs attach to standard mason line or string, while advanced kits may include retractable line reels for convenience. Look for models with clearly marked center points for accurate line attachment.
Frequently Asked Questions
How do I use a plumb bob?
Attach the plumb bob to a string and suspend it from your measurement point. Allow it to hang freely until it stops swinging. The pointed tip will indicate the exact vertical point below, helping you transfer measurements or check alignment.
What’s the difference between a plumb bob and a spirit level?
Spirit levels measure both horizontal and vertical surfaces, while plumb bobs establish vertical reference lines over longer distances, ideal for tall structures or transferring points between floors.
Can plumb bobs be used outdoors?
Yes, but heavier models are better in windy conditions. Brass plumb bobs resist corrosion and avoid magnetic interference, making them ideal for outdoor projects.
