The second positioning element is a platform including an open space that defines a horizontal two-dimensional area where the first positioning element is movable with respect to the open space.

A conduit laser alignment assembly includes a plurality of tubes that each has a unique diameter with respect to each other. 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.

A laser guide device includes a laser for emitting a laser beam along a guide axis. A mounting system is operatively arranged with respect to the laser and is configured for mounting the laser centrally within or adjacent a cylindrical mouth opening of an object. The mounting system includes at least one grip arrangement for mounting the laser guide device on a rim defining the cylindrical mouth opening. The, or each, grip arrangement defines at least one grip formation for bearing against one of a radially outer and a radially inner surface at the mouth opening.
