Description
The Procat plumb bob 400 g is a traditional measuring tool that is still indispensable on building sites, using gravity to create a perfectly vertical line. This 400-gram plumb bob is heavy enough to settle quickly and resist small air currents better than lighter models, which guarantees an accurate measurement even in challenging conditions.
A plumb bob is a simple, reliable way to make sure structures are straight or to transfer an exact measuring point from the ceiling to the floor. It needs no batteries or calibration, as gravity always works reliably. The product is supplied as a ready-to-use pack that includes both the weight and a durable plumb line.
Intended use:
- Ensuring plumb: Checking the straightness of walls, columns, masonry and other vertical structures during construction.
- Aligning points (plumbing): Transferring the exact position of a suspension point from a higher level to a lower level.
- Aligning structures: For example, aligning ceiling battens or partition wall frames directly over marks or structures on the floor.
Package contents:
- 1 x plumb bob (weight 400 g)
- 1 x plumb line (attached to the plumb bob)
Features:
- Optimal weight: The 400 g mass helps the plumb bob settle quickly into a stable vertical line and reduces swinging.
- Precise tip: The shaped tip of the plumb bob points to an exact spot on the surface below.
- Replaceable line: The plumb line supplied can be replaced with a new one when it wears or breaks, which extends the life of the tool.
- Reliable operation: Based on the laws of physics, so the measurement is always reliable with no technical faults.
Technical specifications:
- Weight: 400 g
Instructions for use:
Fix the top end of the plumb line firmly at the required measuring point on the ceiling, a roof truss or another overhead structure. Lower the plumb bob carefully until it hangs freely close to the lower level (e.g. the floor) without touching it. Let the swinging of the plumb bob settle completely. When the plumb bob has stopped completely, the line forms a perfectly vertical line and the tip of the plumb bob points to the exact corresponding point directly below the fixing point.
Warnings:
Always make sure the plumb line is fixed very firmly to the overhead structure. A 400 g metal plumb bob can cause damage if it falls from a height. Wear suitable protective equipment on site, such as a helmet and safety footwear, when working with suspended weights.
Frequently asked questions (FAQ):
Why choose a 400 g plumb bob instead of a lighter one?
A heavier plumb bob, such as this 400 g model, is more stable. It settles from swinging faster and is less sensitive to wind or draughts than lighter plumb bobs, which improves accuracy.
Can the plumb line be replaced?
Yes, the plumb line of the product can be replaced if the original line wears or breaks.
Recycling instructions:
The metal part of the plumb bob can be recycled in metal collection. Dispose of the plumb line (usually nylon or cotton) as mixed waste. Recycle the packaging materials according to local sorting instructions (e.g. cardboard and plastic).
