A retaining assembly secures an equipment item within an aircraft galley compartment. The retaining assembly may include a turn button assembly including a turn button connected to a front edge of the galley compartment to secure the equipment item within the galley compartment. The turn button rotates between a first position for allowing insertion or release of the equipment item from the galley compartment and a second position for securing the equipment item within the galley compartment. A turn button recess on an inner surface of a panel door that is coupled to an edge of an opening for the galley compartment receives the turn button of the turn button assembly when the turn button is in the second position to allow the panel door to fully close over the opening for the galley compartment.
