About Plumb Bobs
Plumb bobs are essential precision tools used to establish a true vertical reference line using gravity. These weighted instruments, suspended from a string or line, have been trusted by tradespeople for centuries to ensure accurate vertical alignment in construction, carpentry, and masonry work. MyToolShed.co.uk stocks a comprehensive range of plumb bobs from leading brands including Draper, Faithfull, Monument, and Tajima, available in both traditional and modern designs.
The selection at MyToolShed includes traditional brass and steel plumb bobs offering durability and reliability, alongside innovative automatic plumblines and all-in-one alignment tools that simplify the levelling process. Whether you need a basic steel plumb bob for general site work or a specialist automatic model for professional applications, MyToolShed.co.uk provides quality options to suit every requirement and budget.
Applications
Plumb bobs are widely used across multiple trades and applications:
- Bricklayers and masons - checking wall verticality and aligning courses
- Carpenters and joiners - establishing vertical reference points for framing and door hanging
- Electricians and plumbers - aligning pipework, conduit runs, and vertical installations
- Surveyors - transferring ground points to overhead positions
- Groundworkers - setting out foundations and establishing vertical datums
- DIY enthusiasts - hanging wallpaper, installing shelving, and general home improvement projects
- Tilers - checking wall alignment before tiling
Choosing The Right Plumb Bobs
Consider these key factors when selecting a plumb bob:
Material: Brass plumb bobs offer excellent weight distribution and corrosion resistance, making them ideal for long-term accuracy. Steel models provide durability and value for general-purpose work. Brass is particularly favoured for precision applications.
Weight: Heavier plumb bobs (typically 200-500g) settle faster and resist wind deflection better on outdoor sites, whilst lighter models suffice for indoor work and confined spaces.
Line Type: Traditional plumb bobs require separate line, whilst automatic plumblines feature integrated retractable cords for convenience and quick deployment on busy job sites.
Tip Design: A replaceable or hardened tip extends the tool's lifespan. Some models include centering features or levelling vials for enhanced functionality.
Application: For general building work, a standard brass or steel plumb bob proves reliable. Specialist tools like the Tajima Plumb Rite offer additional alignment features suited to professional contractors requiring multiple reference points.
Frequently Asked Questions
What's the difference between brass and steel plumb bobs?
Brass plumb bobs are more resistant to corrosion and provide superior weight distribution for precision work, making them preferred for professional applications. Steel plumb bobs offer excellent durability at a lower price point and are suitable for general construction tasks where extreme precision isn't critical.
How long should a plumb bob line be?
Most applications require lines between 3-5 metres, though this depends on your working height. Automatic plumblines typically feature 2.5-3 metre retractable cords suitable for standard ceiling heights, whilst traditional plumb bobs can accommodate custom line lengths for specific requirements.
Can plumb bobs be used outdoors?
Yes, though wind can affect accuracy. Heavier plumb bobs (400g+) resist wind deflection better for outdoor use. For exposed sites, work during calmer conditions or use temporary windbreaks to shield the plumb bob whilst it settles to ensure accurate vertical reference.
