A door system may include a threshold assembly having a base including a base drain channel having a major drain surface inclined from a second edge to a first edge thereof, a base drain hole defined in a second base sidewall to convey water from said base drain channel out through the second base sidewall to an exterior side, on a first base sidewall a first base seat configured for mating seated engagement with a first crown seat in a first seat connection, on the second base sidewall a second base seat configured for mating seated engagement with a second crown seat in a second seat connection, a crown supported by the base, the crown including a crown minor side above the first crown seat and a crown major side above the second crown seat, a crown gutter intermediate the crown minor side and crown major side, a gutter drain hole defined in the crown gutter to convey water into the base drain channel, the crown selectively installable on the base in a first position for in-swing movement of a door element or a second position for out-swing movement of a door element, the crown position selectable independent of the base positioned to convey water from the base drain channel to the exterior side.

A door system has a door jamb assembly with first and second aluminum side jambs, an aluminum head jamb, and an aluminum sill assembly. The first aluminum side jamb encapsulates a first portion of a previously installed first side jamb. The first aluminum side jamb has a screw boss extending from the top end to the bottom end thereof. The second aluminum side jamb encapsulates a first portion of a previously installed second side jamb. The second aluminum side jamb has a screw boss extending from the top end to the bottom end thereof. The aluminum head jamb extends between the top end of the first aluminum side jamb and the top end of the second aluminum side jamb. The aluminum sill assembly extends between the bottom end of the first aluminum side jamb and the bottom end of the second aluminum side jamb.

An outswing sill that is ADA compliant includes a top surface that extends from an outside edge that is configured to be positioned on an exterior side of a door when the door is in a closed configuration to an inside edge that is configured to be positioned on an inner side of the door when the door is in the closed configuration. The top surface has a sealing ramp that increases in height in a direction from the outside edge towards an inside edge. The sealing ramp is configured to be engaged by a door sweep of the door to form a seal with the door sweep when the door is in the closed configuration. The entire top surface having vertical rises of 0.25 inches or less, a total height of 0.5 inches or less, and having a rise:run slope of 1:2 or less.

A grate apparatus for covering a pit defined in a floor of a vehicle wash facility includes a plurality of rigid rung pieces having a first end, a second end, an upper surface and a lower surface. The rigid rung pieces are secured in generally parallel and spaced apart fashion by a plurality of flexible strap members. The flexible strap members are secured to each of the rung pieces by a plurality of fasteners. The grate apparatus is moveable between an unwound position where the first end of each of the plurality of rigid rung pieces rests on one of a pair of spaced apart rails located adjacent the pit and the second end of each of the plurality of rung pieces rests on the other of the pair of spaced apart rails and a wound position wherein the plurality of rung pieces and the plurality of flexible straps are oriented in generally coiled position around a centerline.
