A respective one of the tubes is positionable on an exposed end of an existing conduit in a building that has a diameter corresponding to the diameter of the respective tube. A laser emitter is removably coupled to the respective tube when the respective tube is positioned on the exposed end of the conduit. In this way the laser emitter can emit a beam of light that extends along a longitudinal axis of the existing conduit thereby facilitating the route of a new conduit to be displayed. An adapter disk is provided for coupling the laser emitter to a tube that has a greater diameter than the laser emitter. ## Claims ### Claim 1 A conduit laser alignment assembly being configured to emit a laser beam from an existing conduit for displaying a potential route of newly installed conduit, said assembly comprising: a plurality of tubes, each of said tubes having a unique diameter with respect to each other, a respective one of said tubes being positionable on an exposed end of an existing conduit in a building that has a diameter corresponding to the diameter of said respective tube; a laser emitter being removably coupled to said respective tube when said respective tube is positioned on the exposed end of the conduit wherein said laser emitter is configured to emit a beam of light that extends along a longitudinal axis of the existing conduit thereby facilitating the route of a new conduit to be displayed, said laser emitter having a diameter that corresponds to the diameter of a respective one of said tubes; and an adapter disk being positionable in a respective one of said tubes that has a diameter being greater than the diameter of said laser emitter, said laser emitter being removably coupled to said adapter disk when said adapter disk is positioned on said respective tube for coupling said laser emitter to a tube that has a greater diameter than said laser emitter. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein each of said tubes has a first end, a second end and an outer wall extending therebetween, said outer wall of each of said tubes having an inside surface, said inside surface of said outer wall of each of said tubes being threaded, said first end of said respective tube insertably receiving the exposed end of the conduit. ### Claim 3 (depends on 2) The assembly according to claim 2, wherein said laser emitter has a primary end, a secondary end and an outer surface extending therebetween, said laser emitter being elongated between said primary end and said secondary end, said outer surface being threaded adjacent to said primary end, said secondary end having a light emitter being positioned thereon for emitting the beam of light. ### Claim 4 (depends on 3) The assembly according to claim 3, wherein said outer surface threadably engages said inside surface of said respective tube that has the diameter which corresponds to the diameter of said laser emitter when said respective tube is positioned on the exposed end of the existing conduit. ### Claim 5 (depends on 3) The assembly according to claim 3, wherein said adapter disk has a first surface, a second surface and a perimeter surface extending therebetween, said perimeter surface being threaded, said adapter disk having an aperture extending through said first surface and said second surface, said aperture being centrally positioned on said adapter disk, said aperture having a bounding surface, said bounding surface being threaded. ### Claim 6 (depends on 5) The assembly according to claim 5, wherein said perimeter surface threadably engages said inside surface of said respective tube that has the greater diameter than said laser emitter, said outer surface of said laser emitter threadably engaging said bounding surface of said aperture to retain said laser emitter on said adapter disk. ### Claim 7 A conduit laser alignment assembly being configured to emit a laser beam from an existing conduit for displaying a potential route of newly installed conduit, said assembly comprising: a plurality of tubes, each of said tubes having a unique diameter with respect to each other, a respective one of said tubes being positionable on an exposed end of an existing conduit in a building that has a diameter corresponding to the diameter of said respective tube, each of said tubes having a first end, a second end and an outer wall extending therebetween, said outer wall of each of said tubes having an inside surface, said inside surface of said outer wall of each of said tubes being threaded, said first end of said respective tube insertably receiving the exposed end of the conduit; a laser emitter being removably coupled to said respective tube when said respective tube is positioned on the exposed end of the conduit wherein said laser emitter is configured to emit a beam of light that extends along a longitudinal axis of the existing conduit thereby facilitating the route of a new conduit to be displayed, said laser emitter having a diameter that corresponds to the diameter of a respective one of said tubes, said laser emitter having a primary end, a secondary end and an outer surface extending therebetween, said laser emitter being elongated between said primary end and said secondary end, said outer surface being threaded adjacent to said primary end, said secondary end having a light emitter being positioned thereon for emitting the beam of light, said outer surface threadably engaging said inside surface of said respective tube that has the diameter which corresponds to the diameter of said laser emitter when said respective tube is positioned on the exposed end of the existing conduit; and an adapter disk being positionable in a respective one of said tubes that has a diameter being greater than the diameter of said laser emitter, said laser emitter being removably coupled to said adapter disk when said adapter disk is positioned on said respective tube for coupling said laser emitter to a tube that has a greater diameter than said laser emitter, said adapter disk having a first surface, a second surface and a perimeter surface extending therebetween, said perimeter surface being threaded, said adapter disk having an aperture extending through said first surface and said second surface, said aperture being centrally positioned on said adapter disk, said aperture having a bounding surface, said bounding surface being threaded, said perimeter surface threadably engaging said inside surface of said respective tube that has the greater diameter than said laser emitter, said outer surface of said laser emitter threadably engaging said bounding surface of said aperture to retain said laser emitter on said adapter disk.
