Description Hydraulic level STAYER with reinforced bulbs works on the principle of communicating vessels and is designed for marking work during bricklaying and floor screeding. Thanks to its long hose, it can be used over long distances. Impact-resistant bulbs with protective valves ensure safety during work. Designed for marking and controlling the horizontality of surfaces and structures during construction and installation. The hermetic design allows storing and transporting the level without spilling water. Tight closure of the lid to the bulb is achieved by double clicking. The hole for hanging on the lid of the bulb allows one person to work with the level. Bulbs with scale retain their stability even at sub-zero temperatures. The hose is made of oil and petrol-resistant PVC. Specifications Tube diameter, mm 6 Hose length, m 5
