FAQs
What is a plumb bob used for?
A plumb bob is used to establish a true vertical line. It's a weighted object with a pointed tip on a string, which hangs straight down due to gravity, indicating the vertical direction.
What material is the C.K. Plumb Bob (T3492) made from?
The plumb bob is made of cast iron with a fully polished finish and features a brass cord fitting.
How do I attach the cord to the plumb bob?
The cord attaches via a screwed brass fitting at the top. You unscrew the fitting, thread the cord through, tie it securely to the bob, and then screw the fitting back on to trap the cord.
Is this plumb bob suitable for outdoor use?
Yes, it is suitable for outdoor use, but care should be taken to dry it and store it in a dry place after use to prevent rust.
What is the main advantage of its cast iron construction?
Cast iron provides durability, weight, and stability, which are crucial for accurate vertical alignment, especially in less-than-ideal conditions.
Can I use any type of string with this plumb bob?
It's best to use a strong, thin cord or string that allows the plumb bob to hang freely without excessive drag or snagging.
Troubleshooting
Plumb bob swings excessively and doesn't settle.
Ensure the cord is not snagged and the plumb bob is hanging freely. Check for strong drafts or air currents in the area.
Brass cord fitting is loose.
Unscrew the fitting, check the cord for damage, and re-secure the knot. Ensure the fitting is screwed back on tightly.
Plumb bob appears to be inaccurate.
Verify the plumb line is perfectly vertical by checking against a known vertical surface or using a spirit level. Ensure the plumb bob itself is not damaged.
