Spirit level STABILA Type R 300 — bull's eye level, length 1.22 m, red/yellow

The STABILA Type R 300 spirit level is a bull's eye level with a length of 1.22 m and a red/yellow housing. Designed for quick horizontal levelling checks, it features a circular vial that provides 360° indication for fast and reliable alignment of surfaces and installations. The profile uses a five-chamber ‘R’ design to combine robustness with low weight and high resistance to twisting, while an extra-wide measuring surface reduces the risk of tipping during use. The tool is intended for professional building site conditions where repeated, accurate horizontal reference is required.

Advantages

The five-chamber ‘R’ profile offers increased rigidity and reduced deformation under load, while keeping the level lightweight for comfortable handling. The bull's eye circular vial gives an immediate visual reference for horizontal alignment in any rotational orientation. A wide contact surface improves stability on beams, pipes and flat panels, and the high-contrast colour scheme aids fast identification on busy job sites. The construction is designed to resist impacts and everyday wear typical of construction, carpentry and installation work.

Suitable for

• Horizontal alignment of frames, shelves and furniture during installation
• Quick levelling checks on scaffolding, beams and joists
• Plumbing and HVAC rough-in work where horizontal reference is needed
• Carpentry and joinery where consistent horizontal planes must be established
• Interior fit-out and finishing tasks requiring fast verification of level

Key specifications

• Type: bull's eye circular vial spirit level
• Length: 1.22 m
• Housing colour: red/yellow
• Profile: five-chamber ‘R’ profile for torsional stiffness
• Measuring surface: extra-wide contact area to reduce tipping
• Vial orientation: 360° indication for horizontal levelling

How to use

Place the level on the surface to be checked, ensuring the extra-wide measuring surface makes full contact. Observe the circular vial and rotate the tool if necessary until the bubble is centered, indicating a horizontal plane. For alignment of objects around a central point, position the level at the reference location and use the 360° indication to align all directions. Use steady, light pressure and avoid knocking the level against hard edges to preserve vial accuracy.

Usage recommendations

For best results, store the level on a flat surface when not in use and inspect the vial periodically for clarity and bubble response. Clean contact surfaces to remove dust or debris before taking measurements. When working on irregular or narrow edges, support the level to maintain full contact with the surface. Do not use the tool as a striking instrument or pry bar.
