The Spring Loaded Single Stud Fitting’s distinguishing feature is its integrated spring mechanism unlike other Fitting for L Tracks. Its patented mechanism for self-attachment and self-removal makes connecting and disconnecting easy. While on L tracks, the stud spring loaded makes snapping into position instantaneous. This type of fitting is perfect for applications that require constant repositioning of parts. A prime example is the freight compartments of vehicles where many parts are routinely added and taken off. The spring provides adequate retention of the stud against unintended disconnection during motion or travel.
