Observation windows from size 75 mm upwards are frequently used as observation windows for checking of clutches, limit switches, etc.

Windows used in this way should be easily adjustable and replaceable, to facilitate the adjustment of the particular components. With this in mind, TEPRO observation windows are provided with an external grip/handle, by which they can be removed without difficulty and subsequently returned dust-proof, to their previous position.
