⚡ At a Glance
- • Alignment Accuracy: Well-weighted 140g steel bob combined with a 450cm line gives stable, true vertical readings
- • Best for: Plumbers, joiners, builders, plasterers, decorators and practical DIYers needing quick vertical checks

A 140g steel bob and 450cm line suit household and trade applications. An ergonomic grip helps steady handling for accurate plumb readings.
Reliable vertical reference - with a 140g steel bob
A 140 gram steel bob hangs steadily from the line so gravity produces a true vertical plumb. The weight reduces swing and provides a clear point to mark from when suspended.
Stable suspension leads to repeatable, accurate vertical marks, ideal when aligning frames, tiles or studwork. Well-weighted construction supports precise readings even in light breezes or when held for longer checks.
Long reach for everyday jobs - with a 450cm line
A 450 centimetre line extends to most domestic ceilings and many trade scenarios without needing extensions. The length suits checking vertical alignment across typical room heights and for common fixture installs.
Enough reach for ceilings, partitions and tall fixtures so fewer pauses are needed to re-measure. Handy for both single-room jobs and repeated checks around a site.
Comfortable handling for steady control - with an ergonomic grip
An ergonomic grip is shaped to sit comfortably in the hand, allowing steady control when lowering and holding the bob. Better grip helps reduce hand fatigue during repeated use.
Improved handling makes it quicker to get a true plumb and reduces the chance of slips when marking. Useful for tradespeople who perform many alignment checks in a day.
