Spirit level PRO series 800, painted black, milled vial, 50 cm

Spirit level PRO series 800, painted black, milled vial, 50 cm is a hand tool designed to check horizontal and vertical alignment over a 50 cm span. Manufactured by PRO, this model features a painted black body and a milled vial that improves bubble visibility and seating. It is intended for construction, installation, and general trade tasks where a mid-length, robust spirit level is required.

Advantages

The 50 cm length provides a balance between reach and portability, allowing accurate straightness checks on medium-sized surfaces. The painted black finish resists dirt visibility and gives a uniform appearance while the milled vial offers improved optical clarity and more precise bubble positioning. The level’s construction is aimed at professional and DIY use, providing a stable reference for horizontal and vertical measurements.

Suitable for

• Aligning shelves, cabinets and frames
• Checking wall and floor level during installation work
• Carpentry and joinery tasks requiring a 50 cm reference
• General trade and maintenance jobs where portability matters

Key specifications

• Length: 50 cm
• Finish: painted black
• Vial type: milled (frez) vial for improved visibility
• Measurement axes: horizontal and vertical
• Intended user: trade professionals and DIY

How to use

Place the spirit level on the surface to be measured, ensuring full contact along the body. For horizontal checks, set the level on the surface and adjust the object until the bubble centers between the vial markings. For vertical checks, hold the level against the vertical surface and adjust until the bubble is centered. For longer spans, use the 50 cm length as a straightedge reference; reposition and re-check as needed to confirm continuous alignment.

Usage recommendations

Store the level in a dry place and avoid dropping or striking the vial area to maintain accuracy. Clean the painted surface with a soft cloth to preserve the finish and wipe the milled vial to keep bubble visibility clear. Periodically verify accuracy against a known straight edge or calibrated surface before precision work.
