Abstract
A system for adapting the intake configuration of a central vacuum cleaning system is disclosed. The canister of the central vacuum cleaning system is provided with at least two vacuum intake openings from which an installer can choose to insert an intake coupler and at least one intake closure or cap of the present invention. Insertion and attachment of the intake coupler and the cap(s) is achieved by use of a novel twist-to-lock interface provided between the vacuum intake openings and the coupler and cap(s). Attachment of the coupler and the cap(s) is accomplished easily and quickly by hand and without the need for glue, clamps, tools, or any other equipment.
