Description Stayer hydraulic level with reinforced cylinders works on the principle of communicating vessels and is designed for marking work during brick laying and floor leveling. Thanks to its long hose, it can be used over long distances. Impact-resistant cylinders with protective valves ensure safety during work. They are intended for marking and monitoring the horizontalness of surfaces and structures during construction and installation. The sealed design allows storing and transporting the level without spilling water. The tight fit of the cover to the cylinder is achieved by closing it with a double click. The hole for hanging on the cover of the cylinder allows one person to work with the level. Cylinders with scales maintain stability even at sub-zero temperatures. The hose is made of oil and benzene-resistant PVC. Specifications Tube diameter, mm: 6 Hose length, m: 10
