Spirit level PRO 180 cm with bubble vials for horizontal and vertical measurement and 2% slope indication

PRO spirit level 180 cm is a long, rigid measuring tool designed for accurate horizontal and vertical alignment and for checking a 2% slope over extended spans. The aluminium profile and integrated bubble vials provide clear visual feedback for leveling tasks in construction, installation and workshop environments. This spirit level is intended for jobs where straightness across long distances and reliable inclination control are required.

Advantages

The 180 cm length allows measurement and alignment across larger surfaces with fewer reference points, reducing the need for intermediate supports. Bubble vials for both horizontal and vertical measurement are easy to read and mounted to resist impact and vibration. A dedicated 2% slope indication enables quick verification of gentle gradients without additional tools. The profile construction balances stiffness and manageable weight for comfortable handling on site.

Suitable for

• Carpentry and joinery alignment of beams, cabinets and frames
• Plumbing and drainage slope checks where a 2% gradient is required
• Tiling and flooring installation over long runs
• General construction layout and site setup for straightness checks
• Workshop use for machine and fixture alignment

Key specifications

• Length: 180 cm
• Measuring functions: horizontal and vertical leveling, 2% slope indication
• Vials: bubble vials with clear markings for precise alignment
• Profile material: rigid aluminium profile for reduced flexing
• Mounting and handling: integrated hand-hold and end caps for protection

How to use

Place the spirit level firmly against the surface to be checked and allow the bubble to settle. For horizontal measurements, align the bubble within the central marking of the horizontal vial. For vertical checks, position the level upright and center the bubble in the vertical vial. To verify a 2% slope, use the dedicated vial or marking designed for the 2% indication and compare the bubble position against the slope reference. For long spans, take readings at multiple points along the surface to confirm consistent alignment.

Usage recommendations

Store the level on a flat surface to avoid bending; avoid dropping or striking the vials. Clean contact surfaces before measurement to ensure accuracy and periodically check vial alignment against a certified reference. Use the level within normal temperature ranges to prevent material expansion affecting precision.
