Aluminium Three Vials Level (1000)

The reason length matters is worth stating clearly because it is the whole basis of choosing a level. A level reports only the surface under its own length. Set a long run with a short level and each short segment comes out level while the run as a whole rises and falls, because the tool cannot see between its own ends. The longer the level, the more of the real surface it takes in and the harder it is to be fooled by a local high spot. For anything that has to be true across a distance — a row of units, a course of blocks, a floor — length is accuracy.

Three vials give horizontal, vertical and 45 degrees. At a metre the vertical vial comes into its own, because you can check a door lining or a post over most of its height in one go rather than in stages, and stages are where error accumulates.

The frame is aluminium, which at this length has to be both light enough to handle and stiff enough not to sag under its own weight — a level that bends in the middle reads the bend, not the wall. It is magnetic, which holds it to steel sections, ducting, pipework and machine frames and leaves both hands free.

The buyers are carpenters and joiners, masons and bricklayers, kitchen and shopfitting installers, formwork carpenters, machinery installers, plumbers and HVAC technicians, and hardware dealers supplying building trades.

Check it end for end before you trust it — read a surface, then reverse the level in the same place; the bubble must read the same both ways, and if it does not, everything you have set with it is out. Store and carry it flat or hanging rather than leaning in a corner where it can fall, because a metre of aluminium falling on a concrete floor is exactly what shifts a vial.
