aneThe 092041S13 Stopper is a black spot stopper, manufactured by Fathane, primarily used for installation within aluminum profile extrusions. The stopper is used to create a temporary stop in the groove of the profile, inhibiting the further movement of profile components, such as brackets and profiles, without any further repair or maintenance. The stopper consists of a rotating internal element that can be used to adjust the friction and gripping force of the stopper for various profile sizes. Due to its low friction design, it is suitable for both smooth and coarse groove surfaces and can be reused for multiple operations.
