摘要
The invention concerns a valve stem adjustment device suitable for setting the valve handle to a predetermined height from the wall surface irrespective of the valve recessing depth in the wall. The device is comprised of an extension shaft (4) fitted between the stem (2) of the valve (1) and the valve handle (3) and of a protective bushing (5) enclosing the extension shaft. The extension shaft (4) can be trimmed steplessly according to installation instructions so that the handle (3) of the valve (1) remains at a predetermined height from the wall surface when mounted to the end of the extension shaft.
