Beschreibung
Zusammenfassung:	A length measuring instrument including a hollow profile section extending in a longitudinal direction and an end piece fixed on the hollow profile section for closure of the hollow profile section on an end of the hollow profile section. A scale is disposed inside the hollow profile section, wherein the scale includes a measurement graduation which can be scanned by a scanning unit that is movable in the longitudinal direction relative to the hollow profile section. The length measuring instrument includes a sealing element on the end piece for sealing off the hollow profile section, wherein the sealing element has a cross-section that is at least extensively equivalent to an inside diameter of the hollow profile section. In addition, the sealing element rests sealingly so that a circumferential surface of the sealing element is on an inner face of the hollow profile section.
