Abstract
A threshold assembly includes a base defining a channel, a plurality of nuts slideably engaged in the channel, a rail disposed on the base and defining a plurality of holes, and a plurality of threaded fasteners rotationally retained in the holes and threadedly engaging the nuts. The channel has a neck and a pair of opposing sides angling outwardly from the neck into the base. Each nut presents opposing contact surfaces complimentary to the opposing sides of the channel such that the nut is slideably engaged in the channel. The nut also includes an elongated platform such that when the threaded fastener is rotated, the elongated platform and the opposing contact surfaces of the nut engage the opposing sides of the channel such that the height of the rail relative to the base is adjusted in response to rotation of the threaded fastener relative to the nut.
