## Summary description

A 400 cm spirit level from Level PRO Mason's, model 3-01-02-20-400. Designed for long straightedge and alignment tasks, it provides a precise reference for masonry, construction and carpentry work. The long length aids in checking level and plumb over extended surfaces, improving accuracy and efficiency on-site.

## Long description

The Spirit level Level PRO Mason's 400 cm model 3-01-02-20-400 is a long-format measuring tool designed for establishing level and plumb across extended surfaces. With a four-metre length, it provides a straight reference for masonry, construction and carpentry applications where accuracy over distance is required. The profile and vial placement are arranged to assist in checking horizontal and vertical alignment and to maintain consistent reference lines on walls, floors and structural elements.
Advantages
This 400 cm spirit level offers a stable, extended straightedge that reduces the need for multiple shorter levels or repeated measurements. The length improves the ability to detect small deviations across large surfaces, supporting more accurate installation of masonry courses, formwork, and long timber or steel elements. The tool is intended for professional and site use where a single precise reference across several metres is beneficial.
Suitable for
 Masonry laying and checking courses over long walls
 Leveling formwork and concrete screeds
 Aligning long timber beams and structural elements
 Checking straightness and planarity of floors and façades
 General construction and carpentry layout tasks
Key specifications
 Length: 400 cm
 Primary function: horizontal and vertical leveling
 Suitable working range: long-format alignment up to four metres
 Typical applications: masonry, formwork, carpentry, façade and floor alignment
 Construction: long straightedge profile designed for on-site durability
How to use
Place the spirit level along the surface or edge to be checked, ensuring firm contact along its length. For horizontal checks, position the level on the underlying reference surface and read the central vial to determine level; adjust the workpiece or formwork until the bubble is centered. For vertical checks, hold or brace the level against the vertical element and read the vertical vial. For long runs, move the level along the surface and verify that successive readings maintain the same reference, making incremental adjustments as needed. Handle the tool carefully during transport and on-site to preserve straightness.
Usage recommendations
Use the spirit level on clean, debris-free surfaces for best accuracy. Support the level at intervals on very long spans to avoid flexing; when storing or transporting, keep it protected from heavy impacts or bending to maintain its straightness and measurement reliability.
