Abstract
A plug includes a conformable element and a structural cover or top plate for plugging a hole in a concrete floor slab. This permits a workman to plug the hole; unplug the hole; and, in some embodiments, fit a pipe through the hole. Moreover, the conformable element may be swapped-out on site, allowing a workman to adjust a diameter and outer surface of the plug to meet on-site conditions.
