EX-AGL Stainless Steel Angle Box is a wall-mounting accessory for the HFX Quadra door station. You use it to angle the unit toward visitors when a flat wall installation does not give the camera a direct view. The box is constructed from stainless steel for outdoor use and long-term durability. It matches the finish of the HFX Quadra and resists corrosion in urban and coastal environments. The angled design improves camera visibility and audio pickup by reducing blind spots. It also provides clean cable routing and a solid mounting surface without altering the door station. EX-AGL is used in multifamily and commercial installations where proper camera coverage and a clean appearance are required.
