Card GuidesCard guides are components used in boxes, enclosures, and racks to securely hold and organize printed circuit boards (PCBs) or other types of cards. They are typically made from plastic or metal, and consist of a series of slots or channels that the cards can be inserted into. The guides help to keep the cards in place and prevent them from becoming loose or damaged. They also help to organize the cards in a neat and orderly fashion, making it easy to access and remove individual cards as needed. Card guides are commonly used in computer systems, telecommunication equipment, and other types of electronic devices.
