This invention provides a coupler having universal adaptors for compressed air, fluid, electricity, and/or data that enable a user to connect existing hoses or cords to the coupler, which is attached to a door base and/or window sash, thus allowing the door and/or window to be fully opened and closed. The body of the coupler is a U shaped clamp. The body has a thin base plate that is positioned under the door and/or window and two walls that contain electrical/pneumatic/data connectors. In one embodiment, the body is made of a durable plastic. The clamp is tightened via a tension screw with an adjustment knob or by a screwdriver. Embedded within the body are channels that allow passage of electricity, air, fluid, and/or data packets.
