Examples provide an attachment frame for combination attachment of environmental control devices. A plurality of non-articulating, rigid segments within a main body bend at various fixed angles. A perpendicular support arm forms an “L-shaped” attachment at the top of the main body. The support arm mounts one or more lights which attach to a top surface of the support arm. A bottom surface of the support arm mounts a fan or heater above a conveyor or other work area. The attachment frame includes a container holder to hold a water bottle or other container. A mounting plate connected to segment at the bottom of the main body mounts to the trailer conveyor device or other equipment. The attachment frame provides light, ventilation and/or temperature control for users working within an interior of a trailer or other confined spaces.
