Rothoblaas Tape Measures, Spirit Levels and Markers

Although often considered a preliminary task, dimensional control on site is a critical aspect of contemporary timber construction, with direct implications for system stability and adherence to performance parameters.
Errors in alignment, dimensional checks or fastening-point markings create problems that can spread to the entire structure, affecting flatness, design geometry and joint performance.

This is why tape measures and rules, professional spirit levels, markers and squares must be regarded as structural carpentry tools, on par with fastening systems or installation tools.
The Rothoblaas range for use on site combines durable materials, precise readability and ease of use, making measurement a reliable, repeatable process.

Linear measurement: Construction tape measures designed for continuous use

Checking lengths, alignment and spacing is a task that runs through every stage of assembly, from laying the first elements to completing the final details.
Accordingly, a construction tape measure must provide reliable readings even after repeated extension cycles, accidental knocks and changing environmental conditions.

Rothoblaas tape measures are made from high-strength materials, and every component – from the casing to the joints on folding wooden rules – is built to last. A tool that remains stable over time helps keep tolerances consistently within project specifications.

These are all characteristics shared by RBMET, the carpenter's folding rule, the SNAIL measuring tape and MANTA.

Geometric checks: Spirit levels for verticality and flatness

Verifying vertical and horizontal alignment is another recurring task, applicable to wall assembly, frame installation and floor flatness checks.
Rothoblaas professional spirit levels combine rigid aluminium profiles with functions that enable fast, consistently reliable readings.

In addition to a backlit LCD display with large digits for immediate readability, the Rothoblaas spirit level range also includes models that measure in degrees, percentages, millimetres/metres and inches/feet, with illuminated displays and precision acoustic indicators.

A reliable spirit level reveals deviations straight away, which, if left uncorrected, can lead to cumulative errors across multiple storeys or sequential assemblies. The stability of the profile ensures consistent readings even under load or when resting on surfaces that are not perfectly even.
With HERON ANGLE, angle calculations are consistently accurate thanks to a zeroing function that can be set in any position. 

Marking and layout: Defining lines, axes and reference points

Marking operations affect cuts, holes, the positioning of connectors and the definition of internal alignments. A marking tool must lay down a continuous, visible line that lasts throughout every stage of work.

COSMOS and CHAMELEON feature stretch-resistant cords, steel spring rewind systems, and integrated hooks making them quick and easy to position.

Thanks to powder cartridges available in different colours, the layout lines can be colour-coded, with different meanings assigned to each marking, thus reducing the risk of misinterpretation when installing components.

Carpentry squares: Checking squareness and assembly angles

Squareness is an essential geometric requirement in timber structures, especially in CLT walls and floors, where even slight rotations can introduce unwanted stresses into the joints.

Rothoblaas squares are made from stainless steel and feature laser-engraved markings that maintain their readability and precision over time.
The thin measuring edge allows the tool to sit flush against the material, preventing errors caused by the thickness of the instrument.

These tools are useful for:

• checking 90° angles on prefabricated elements;

• ensuring correct geometry in secondary beams;

• verifying that elements fabricated off site will fit correctly when assembled on site.

A stable, non-deformable square reduces the risk of discrepancies between the actual geometry and the design geometry, especially in modular systems.

Measuring tools as part of the construction process

Dimensional control should not be regarded as a standalone step, but as part of a continuous cycle: preparation → verification → correction → installation → final check.

Thanks to their robust materials and precise readout components, Rothoblaas measuring tools help maintain consistent execution quality throughout every stage of assembly.
