Description STAYER Hydrolevel with reinforced bulbs operates on the principle of communicating vessels and is designed for marking work when laying bricks and leveling floors. Thanks to its long hose, it can be used over long distances. Shock-resistant bulbs with protective valves ensure safety during work. They are designed for marking and monitoring the horizontal surfaces and structures during construction and installation. The hermetic construction allows storing and transporting the level without spilling water. A tight seal between the lid and the bulb is achieved by double-click closure. The hole for hanging on the lid of the bulb allows for one-person use of the level. Bulbs with a scale maintain stability even at negative temperatures. The hose is made of oil and gasoline resistant PVC. Specifications Tube diameter, mm 6 Hose length, m 15
