The doorsill has a substrate to be disposed above a subfloor and a lifter provided on the substrate capable of extending from a bottom of the substrate. The lifter is adjustable to change the orientation or position of the bottom relative to the subfloor. ## Claims ### Claim 1 A doorsill comprising: a substrate having a length, a width, and a top side; at least one mullion spacer having a top surface and being selectively positioned along the length of the substrate; the at least one mullion spacer extending upwardly from the top side of the substrate; the at least one mullion spacer being configured to underlie and support a mullion post extending upwardly from the doorsill and to space a bottom end of the mullion post above the top side of the substrate; and a sill deck secured to and covering a portion of the substrate, the sill deck being formed with a notch surrounding the at least one mullion spacer. ### Claim 2 (depends on 1) A doorsill as claimed in claim 1 wherein the at least one mullion spacer is secured to the substrate. ### Claim 3 (depends on 2) A doorsill as claimed in claim 2 further comprising a post depending from the at least one mullion spacer and into a receptacle formed in the substrate to secure the mullion spacer. ### Claim 4 (depends on 3) A doorsill as claimed in claim 3 wherein the receptacle comprises an attachment channel formed in the top side of the substrate and extending along the length direction of the substrate. ### Claim 5 (depends on 4) A doorsill as claimed in claim 4 further comprising crush ribs associated with the channel configured to create a friction fit with the post of the at least one mullion spacer. ### Claim 6 (depends on 5) A doorsill as claimed in claim 5 wherein the channel is sufficiently elongated to allow for placement of the at least one mullion spacer along the substrate in the proper location for supporting a mullion. ### Claim 7 (depends on 1) A doorsill as claimed in claim 1 further comprising a mullion post extending upwardly from the at least one doorsill and supported upon the at least one mullion spacer. ### Claim 8 (depends on 1) A doorsill as claimed in claim 1 wherein the substrate has an outside edge for facing the outside of a building and wherein the sill deck can be slid in the direction of the outside edge to remove the sill deck from the substrate while leaving the at least one mullion post in place supported upon the at least one mullion spacer. ### Claim 9 (depends on 1) An entryway comprising a right jamb, a left jam, a mullion post, and a header, the right jamb and the left jamb extending upwardly from respective ends of the doorsill claimed in claim 1 and the mullion post resting on the mullion spacer of the doorsill claimed in claim 1. ### Claim 10 (depends on 9) An entryway as claimed in claim 9 further comprising at least one door panel hingedly mounted in the entryway and movable between a closed position and an open position. ### Claim 11 (depends on 1) An entryway as claimed in claim 1 wherein the top surface of the at least one mullion spacer is smaller than a bottom surface of a mullion post so that a bottom surface of the mullion post overlaps and hides a portion of the sill deck around the at least one mullion spacer. ### Claim 12 A door assembly for an entryway, the door assembly comprising a doorsill, a left jamb with a bottom end, a right jamb with a bottom end, and a mullion with a bottom end, the mullion being located between the left jamb and the right jamb, the doorsill comprising: a substrate for mounting on a subfloor of a building entryway, the substrate having ends and an outside edge; a sill deck secured to and covering at least a portion of the substrate, the sill deck being selectively removable from the substrate by sliding the sill deck in the direction of the outside edge of the substrate; a mullion spacer mounted on the substrate and extending upwardly therefrom, the mullion spacer being located along the length of the substrate such that it will underlie and support the bottom end of the mullion of the door assembly; the sill deck having a cut-out with edges that at least partially surround the mullion spacer; and when the sill deck is slid in the direction of the outside edge of the substrate for removal, the cutout moves away from the mullion spacer leaving the mullion spacer to support the bottom end of the mullion on the substrate. ### Claim 13 (depends on 12) The doorsill of claim 12 wherein a top surface of the mullion spacer is smaller than the bottom end of a mullion to be supported on the spacer so that the bottom end of a mullion overlaps a portion of the sill deck around the mullion spacer. ### Claim 14 (depends on 12) The doorsill of claim 12 further comprising a post extending downwardly from the mullion spacer and into a receptacle on the substrate to hold the mullion spacer in place on the substrate. ### Claim 15 (depends on 14) The doorsill of claim 14 wherein the receptacle comprises an elongated channel extending in the direction of the length of the substrate allowing the mullion spacer to be located selectively along the channel to underlie the bottom end of a mullion. ### Claim 16 (depends on 15) The doorsill of claim 15 further comprising structures associated with the elongated channel to secure the downwardly extending post of the mullion spacer in the channel ### Claim 17 (depends on 16) The doorsill of claim 16 wherein the structures comprise crush ribs that create a friction fit with the post of the mullion spacer. ### Claim 18 A doorsill assembly for an entryway, the doorsill assembly comprising an elongated substrate, a sill deck covering at least a portion of the elongated substrate, and a mullion spacer located along the length of the substrate to underlie and support the bottom end of a mullion above a top surface of the substrate, the sill deck being formed with a notch that receives the mullion spacer so that the sill deck may be removed from the substrate leaving the mullion spacer in place supporting a mullion above the substrate. ### Claim 19 (depends on 18) A doorsill assembly as claimed in claim 18 wherein the mullion spacer and the notch are smaller than the bottom end of a mullion so that the bottom end of a mullion covers the mullion spacer and a portion of the sill deck around the notch to hide the mullion spacer and create the appearance that the bottom end of the mullion rests on the sill deck. ### Claim 20 (depends on 18) A doorsill assembly as claimed in claim 18 wherein the mullion spacer is secured to the substrate with a post extending downwardly from the mullion spacer and into a receptacle formed on the substrate. ### Claim 21 (depends on 20) A doorsill assembly as claimed in claim 20 wherein the receptacle comprises a channel extending lengthwise along the substrate so that the mullion spacer may be located at a predetermined position along the channel. ### Claim 22 (depends on 21) A doorsill as claimed in claim 21 further comprising crush ribs in the channel that create a friction fit with the post of the mullion spacer. ### Claim 23 (depends on 19) A doorsill as claimed in claim 19 further comprising at least one second mullion spacer located along the length of the substrate to underlie and support the bottom end of a second mullion above a top surface of the substrate, the sill deck being formed with a second notch that receives the second mullion spacer.
