ABSTRACT:
A selectively sealable drain fitting includes a tubular drain body having a spider in the lower end thereof. An upwardly extending rectangular post is joined to the center of the spider, and is provided with a lateral slot in one face thereof and an oblique camming surface directly superjacent thereto. A drain sealing cover is provided with a downwardly depending hollow tubular portion which is received about the rectangular post and maintained in an eccentric disposition thereabout by an eccentric lip extending laterally from the upper end of the post. A latch pin extending laterally through the tubular portion of the cover engages the camming surface and the slot in the post in detent fashion. A button actuator extends upwardly from the center of the cover, and is connected to an arm which is slidably disposed within a slot in the bore of the tubular member. The drain fitting is sealed by urging the cover downwardly so that the latch pin is engaged by the slot. The cover is released by pushing the button in the cover to translate the arm and release the latch pin from the slot.
