What is a Knockout? | Definition of a Knockout - Apex Granite Outlet

In the context of kitchen cabinets, a knockout refers to a pre-drilled hole on the back panel or the sides of the cabinet. Knockouts are designed to allow for easy access to power sources and other utilities that may be needed within the cabinet. They are typically created during the manufacturing process and are covered with knockouts caps when not in use. Knockouts can also be used to facilitate the installation of cabinet accessories such as lighting fixtures, ventilation systems, and pull-out trays.

There are different types of knockouts used in kitchen cabinets. The most common ones are round knockouts which are usually 2 inches in diameter. They can be placed on the top, back, or sides of the cabinet. Another common type is rectangular knockouts, which are larger and wider than the round ones. Rectangular knockouts are often used for pull-out trays or other large appliances that need to be installed within the cabinet. Some cabinets may also have custom knockouts, which are designed to fit specific accessories or components.

When designing a kitchen cabinet layout, it is important to consider the placement and size of knockouts. The number and location of knockouts may affect the functionality and accessibility of the cabinet. For example, if a cabinet will house a small appliance like a coffee maker, it may require a round knockout on the top or back panel to allow for easy access to the power source. On the other hand, a cabinet with a pull-out tray or a large appliance may need multiple rectangular knockouts on the sides or back panel to accommodate the necessary connections. In some cases, it may be necessary to customize the knockouts to fit the specific requirements of the appliance or accessory being installed.
