The Harloff Metal Black Balloon Storage Unit is a heavy-duty, specialty clinical accessory designed for secure, organized storage and rapid retrieval of intra-aortic balloon pumps (IABP), cardiac catheterization balloons, and specialized interventional care equipment. Constructed from commercial-grade steel with a durable, scratch-resistant black powder-coat finish, this rack assembly integrates seamlessly onto compatible Harloff medical carts, specialty procedure cabinets, and clinical storage frames. Designed to hold up to five large balloon storage boxes or pouches in an upright, highly visible orientation, this field-mountable unit prevents packaging damage, protects delicate balloon catheters, and streamlines stock rotation in critical care, cardiac cath labs, and emergency surgical suites.
