Spirit level STABILA Type R 300 — 1.83 m, dual-colour red/yellow, accuracy ±0.5 mm/m

STABILA Type R 300 is a 1.83 m spirit level engineered for accurate horizontal and vertical alignment on construction and installation tasks. The dual-colour red/yellow aluminium profile combines visibility with a torsion-resistant five-chamber 'R' design that delivers long straightness and stability. With a levelling accuracy of ±0.5 mm/m in both normal and reversed positions, this level provides reliable vial readings for carpentry, masonry, framing and HVAC alignment where a long, precise straightedge is required.

Advantages

The R 300 is extremely robust yet lightweight thanks to its aluminium 'R' profile and continuous bridge over the horizontal vial that increases rigidity. An extra-wide measuring surface prevents tipping during use and the coated measuring faces protect delicate materials. Shock-absorbing, removable end caps and an anti-slip stopper ensure impact protection and firm seating when marking. Three marking and cutting edges run the full length for exact layout work, while a full-length handrail with finger groove improves grip when carrying and measuring.

Suitable for

• Carpentry and joinery alignment and marking
• Masonry and plaster leveling tasks on-site
• Framing, stud-work and structural alignment
• HVAC and installation work requiring long straight references
• Precise marking and cutting over long distances

How to use

Place the STABILA Type R 300 on the surface to be checked and allow the bubble to settle within the vial to determine level or plumb. For horizontal measurements use the central horizontal vial; for vertical alignment use one of the vertical vials. Use the extra-wide measuring surface to prevent tipping and, when necessary, remove the end caps for marking close to corners. Use the full-length marking edges to scribe or guide cutting along the profile. Clean the coated measuring surfaces after use to maintain accuracy.

Usage recommendations

Store the level on a stable surface and avoid severe impacts; replace removable end caps after work. Periodically check accuracy in both normal and reverse positions and clean the coated surfaces to preserve measuring precision. Use the handrail with finger groove for controlled handling during transport and measuring tasks.
