Abstract: A system for and a method of preventing a conduit, pipe, or other similar traversing piece of equipment, from falling through an opening, and for facilitating ready adjustment of the traversing piece of equipment during installation, maintenance, and/or repair services. A first embodiment may involve a single-component system or a multi-component system. A second embodiment may involve a multi-component system for and method of effectively increasing the diameter of a conduit or pipe to an amount greater than that of an opening, but in a way such that the conduit or pipe can be adjustably extended without need for disengaging the system or back-tracking/reversing the method. A third embodiment may involve an annular riser ring and method of use thereof, wherein the riser ring is configured to slide over a conduit or pipe and is held in place along the pipe or conduit by a tight but slidable friction fit.
