发明名称 Ceiling wiring access point device
摘要 A ceiling wiring access point device is comprised of a frame panel that can be temporarily placed in a grid ceiling system during the installation of wire and cable into a ceiling space. The frame panel has an opening through which wire and cable may be inserted as it is threaded up into the ceiling. The internal edges of the opening are provided with roller members to provide a relative frictionless edge against which the wires may pass. Dust guards are provided at the opening to prevent debris from the ceiling area from falling to the room below.
