Line of sight blocking grille assembly

A grille assembly, comprising:

• a housing comprising a room facing end having a first opening, a duct facing end having a second opening, and a corridor extending between the first opening and the second opening;
• and
• a core configured to translate through the second opening, into the corridor, and toward the first opening, wherein the core comprises:
• a first plurality of blades slanted in a first direction at a first non- perpendicular angle relative to a corridor axis, wherein the first plurality of blades forms a first plurality of channels that partially pass through the housing in an installed configuration of the core;
• and
• a second plurality of blades slanted in a second direction, substantially opposite the first direction, at a second non-perpendicular angle relative to the corridor axis, wherein the second plurality of blades forms a second plurality of channels that partially pass through the housing in the installed configuration of the core,
• wherein the second plurality of blades is configured to translate through the second opening into the corridor independently of the first plurality of blades, and
• wherein the first plurality of channels and the second plurality of channels are arranged to obstruct a line of sight through the corridor from the room facing end to the duct facing end of the housing.

A grille assembly, comprising:

• a housing comprising a first end having a first opening, a second end having a second opening, and a corridor extending between the first opening and the second opening;
• a first core unit comprising a first plurality of blades spaced apart relative to one another and slanted in a first direction and at a first angle, wherein the first core unit is configured to be disposed within the corridor;
• and
• a second core unit separate from the first core unit and comprising a second plurality of blades spaced apart relative to one another and slanted in a second direction, substantially opposite the first direction, and at a second angle,
• wherein the first core unit is configured to translate through the second opening into the corridor independently of the second core unit, the second core unit is configured to translate through the second opening into the corridor independently of the first core unit, the first core unit and the second core unit are configured to abut one another within the corridor, and the first plurality of blades and second plurality of blades form a plurality of channels extending from an inlet defined by the first core unit to an outlet defined by the second core unit, and wherein each channel of the plurality of channels is deviated to obstruct a line of sight through the corridor from the first end to the second end of the housing.
