Abstract: A cover for sealing floor penetrations formed from a unitary, continuous piece of thermoplastic material having a rim portion and a recessed portion. The rim portion forms a flange having an outer edge, and the recessed portion extends downward from the rim portion and defines a cavity. The flange portion extends past the floor penetration to contact and rest on the floor, and adhesive layers may be used to create a seal between the cover and the floor.

Abstract: A door sill apparatus for a manufactured home comprising a substrate having an inner edge and an outer edge and a threshold member configured to be removably secured to the substrate, the threshold member having a deck at least partially covering the substrate, an upper surface, an opposing lower surface, and a deck support having a base leg, a drip leg, and a cross support connecting the base leg to the drip leg. The base leg and drip leg extend downward from the deck such that the base leg contacts the subfloor of the manufactured home, reinforcing the threshold member. The drip leg extends below the plane in which the subfloor and substrate, preventing water intrusion. The cross member connects the base leg and the drip leg and stiffens and reinforces the portion of the deck extending past where the base leg extends downward.
