Pull string vacuum assembly
A pull string management system. The Pull String Vacuum Assembly that includes a cover plate which encompasses a junction box and a port which coincides with a standard shop vac hose is provided. The cover plate is constructed in such a way as to fit over a junction box and utilizes a seal to create a vacuum over the entirety of a junction box for the purpose of moving pull string or wire through new or existing conduit. The port is constructed in such a way as to coincide with a standard shop vacuum hose and requires no additional attachments or modifications.
1 . A Pull String Vacuum Assembly, for attachment to an electrical junction box during installation of electrical wiring through conduit, the assembly comprising:
a substantially planar cover plate having a front surface, a rear surface, and a central opening extending through the cover plate;
a flange extending outwardly from the front surface of the cover plate and surrounding the central opening;
a tubular gasket positioned on the rear surface of the cover plate and surrounding the central opening, the tubular gasket being configured to form a seal against the electrical junction box; and
an adhesive securing the tubular gasket to the rear surface of the cover plate.
2 . The pull string vacuum assembly of claim 1 , wherein the cover plate is formed from polyvinyl chloride (PVC) or polycarbonate material.
3 . The pull string vacuum assembly of claim 1 , wherein the cover plate is rectangular or square in shape.
4 . The pull string vacuum assembly of claim 1 , wherein the flange is integrally formed with the cover plate as a single molded component.
5 . The pull string vacuum assembly of claim 1 , wherein the tubular gasket is formed from rubber, silicone, or vinyl material.
6 . The pull string vacuum assembly of claim 1 , wherein the adhesive comprises an industrial adhesive configured to secure the tubular gasket to the rear surface of the cover plate.
7 . The pull string vacuum assembly of claim 1 , wherein the removable flanged adapter is formed from transparent PVC material.
8 . The pull string vacuum assembly of claim 1 , wherein the stepped sections of the removable flanged adapter define progressively larger internal diameters configured to receive vacuum hoses of different sizes, wherein the pull string vacuum assembly is configured to generate vacuum airflow through electrical conduit to facilitate routing of a pull string through the electrical conduit.
9 . The pull string vacuum assembly of claim 1 , wherein the removable flanged adapter further includes internal stepped openings configured to receive electrical conduit of different diameters.
10 . An oversized pull string vacuum cover assembly for use with oversized electrical junction boxes, the assembly comprising:
an oversized cover plate having a central opening;
a flange extending around the central opening;
a tubular gasket positioned on a rear surface of the oversized cover plate; and
an adhesive securing the tubular gasket to the oversized cover plate.
11 . The oversized pull string vacuum cover assembly of claim 10 , wherein the oversized cover plate is rectangular or square in shape.
12 . The oversized pull string vacuum cover assembly of claim 10 , wherein the flange is configured to removably receive a stepped vacuum adapter.
