Carpenter's hose level Cellfast 20 m transparent

Cellfast Carpenter's hose level, 20 m transparent, is a simple liquid-filled leveling tool designed for transferring horizontal reference points over long distances. The transparent tube contains a visible liquid column that equalizes to the same level at both ends, enabling accurate alignment of foundations, trenches, fence posts and irrigation lines. The 20 m length is suitable for most small-to-medium construction and landscaping tasks where a portable, lightweight solution is required.

Advantages

The transparent tubing provides clear visibility of the liquid line for fast readings without electronic components. Its 20 m reach allows measurement and transfer of level across larger sites while remaining compact and easy to coil for storage. The simple design is low-maintenance and tolerant of rough handling on construction sites. The tool is ready to use with minimal setup and does not require calibration or power, making it practical for outdoor and remote jobs.

Suitable for

• Aligning foundations and footings over distance
• Setting fence posts and gate frames to the same level
• Leveling trenches, drainage lines and irrigation channels
• Transferring benchmark heights between rooms or across obstacles
• DIY landscaping and small construction projects

Key specifications

• Tube length: 20 m
• Tubing type: transparent flexible hose
• Leveling medium: sealed visible liquid column
• Portability: lightweight, flexible for coiling and transport
• Usage environment: outdoor and indoor use, tolerant to typical jobsite conditions

How to use

To use the hose level, uncoil the transparent tube and position the two ends at the points where level needs to be transferred. Fill or prime the tube as needed so the liquid column reaches both ends, then allow the liquid to settle until both visible menisci align at the same height. Hold the reference end steady while a second person reads and marks the matching height at the remote end. For repeating measurements, keep the tube free of kinks and air bubbles and re-settle the liquid before each reading.

Usage recommendations

Store the hose coiled in a dry place away from sharp objects and extreme temperatures. Before each use check the tube for cracks or leaks and remove large air bubbles by gently shaking or inverting the hose. When working in cold conditions, keep the liquid from freezing by storing the tool in a warmer location until ready to use. Avoid dragging the hose over abrasive surfaces to prolong service life.
