A maintenance device for use in a liquid ejection apparatus including a liquid ejection head with a nozzle forming surface provided with nozzle for ejecting a liquid. One aspect of the invention includes a lighting fixture with a visor. During the rough-in plumbing phase of construction, a test cap welded in the drain pipe seals the drain line from the sewer line at the location of the clean-out. Pressure exerted by the ram is transferred to the cover-plate through the contact surface, deforming and expanding the cover-plate in a predetermined manner to close the socket housing.
