Wire tray and mounting insert assemblies
This publication describes techniques and apparatuses for releasably attaching an object (e.g., a wire tray) to a substrate. Current apparatuses generally do not enable the removal of an attached wire tray from a substrate without first removing an insert from a mounting stud extending from the substrate. The disclosed techniques and apparatuses are configured to permit the removal of an attached wire tray from a substrate without first removing an insert from a mounting stud extending from the substrate.
