VOREL 17303 plumb bob

The VOREL 17303 plumb bob is a masonry plumb bob designed for vertical alignment and marking in construction and related tasks. It combines a turned steel body with a lacquered finish and a braided rope to provide reliable, visible vertical reference over distances up to 6 m. The compact, conical shape and balanced weight make it suitable for transferring plumb lines and checking vertical planes on masonry, formwork and installation work.

Advantages

The plumb bob features a turned steel body with a lacquered surface that resists light corrosion and mechanical wear. Its conical geometry and 200 g weight ensure stable hanging and rapid damping of swing when suspended. Supplied with a 6 m braided rope, it provides sufficient length for most site applications while remaining easy to handle and store. The simple, robust design requires no power or calibration.

Suitable for

• Vertical alignment of walls and masonry
• Setting out and checking plumb on formwork and frames
• Transferring reference points between floors and levels
• Use in renovation, carpentry and general construction tasks

Key specifications

• Body material: turned steel with lacquered finish
• Effective length of body: 115 mm
• Body diameter (widest): 22 mm
• Weight: approximately 200 g
• Rope type and length: braided rope, 6 m

How to use

Secure one end of the braided rope at the required reference point and suspend the plumb bob so it can hang freely without obstruction. Allow the bob to come to rest before taking readings or marking the vertical line. For transferring points between different levels, ensure the rope runs freely and is held steady at both ends. When finished, wind the rope neatly and store the plumb bob in a dry place to maintain the lacquered finish.

Usage recommendations

Use the plumb bob on a stable anchoring point and avoid strong drafts while taking measurements. For improved visibility on dark surfaces, pair the device with a contrasting chalk or marker. Inspect the rope and attachment point regularly for wear and replace if frayed.
