## Long description

PRO 40 cm spirit level model 100-04 is a compact measuring tool for checking horizontal and vertical alignment over a 40 cm length. It integrates a horizontal vial and a vertical vial in a lightweight, rigid body designed for workshop, on-site and DIY use. The spirit level is intended to provide quick visual verification of straightness and plumb for carpentry, installation and general construction tasks where a mid-length reference is required.
Advantages
The spirit level combines a clear, easy-to-read horizontal vial and a vertical vial placed for precise sighting. Its 40 cm length balances portability with sufficient span for many alignment tasks. The rigid profile resists bending during handling and offers stable contact with work surfaces. The tool’s compact size and simple construction make it straightforward to use, store and carry between job sites.
Suitable for
 Carpentry work: checking cabinet, shelf and frame alignment
 Installation: fitting fixtures, plumbing lines and window/door frames
 DIY projects: shelving, picture hanging and small renovation tasks
 Workshop measurements: setting up jigs and verifying machine alignment
Key specifications
 Measuring length: 40 cm
 Vials: integrated horizontal and vertical spirit vials
 Body: rigid profile for stable contact
 Weight: lightweight design for portability
 Intended use: manual checking of level and plumb
How to use
Place the spirit level on the surface to be checked, aligning the body along the reference edge. For horizontal checks, position the level so the horizontal vial is centered and read the bubble position to determine levelness; for vertical checks, align the vertical vial and observe the bubble to determine plumb. For longer runs, mark points using the level at multiple positions or use the tool as a reference while adjusting the workpiece until the bubble centers. Store the level in a dry place to preserve vial clarity and accuracy.
Usage recommendations
Handle the tool gently to avoid shocks that could displace the vials. Verify vial readability before critical tasks and recalibrate or replace the tool if bubbles no longer rest consistently at center when checked on a known level surface.
