a mounting frame; and
an active door panel mounted in and capable of sliding relative to the mounting frame, the active door panel suitable for use as a hinged door panel, wherein the active door panel has a face including a panel portion and a glazing portion, wherein the glazing portion comprises less than 65% of a surface area of the face.
2. The sliding door unit of claim 1 , further comprising a fixed door panel fixed to the mounting frame,
wherein in a closed position of the sliding door unit, the active door panel is adjacent to and substantially coplanar with the fixed door panel.
3. The sliding door unit of claim 2 , wherein, in the closed position, a margin between adjacent edges of the active door panel and the fixed door panel is substantially sealed by a pair of astragals attached to the active door panel and fixed door panel respectively.
4. The sliding door unit of claim 3 , wherein an astragal of the pair of astragals is attached to the active door panel along a second side edge of the active door panel opposite the first side edge, and wherein the astragal houses a lock, the lock comprising at least one shoot bolt and an actuator.
5. The sliding door unit of claim 1 , wherein the active door panel is retained within the mounting frame by guide roller assemblies mounted adjacent to a bottom edge and a top edge of the active door panel.
6. The sliding door unit of claim 5 , wherein the guide roller assemblies ride within guide slots formed in a sill and a header of the mounting frame.
7. The sliding door unit of claim 6 , wherein the guide slots are non-linear.
8. The sliding door unit of claim 5 , wherein the guide roller assemblies are mounted in mortise grooves formed in the first side edge of the active door panel, wherein the mortise grooves intersect the respective top and bottom edges of the active door panel.
9. The sliding door unit of claim 5 , wherein the guide roller assembly assemblies comprise roller bearings that are adjustable relative to a top and bottom edge of the active door panel from a side edge of the active door panel.
10. The sliding door unit of claim 1 further comprising a latch configured to selectively prevent sliding movement between the active door panel and the mounting frame, the latch comprising:
at least one pair of pawls configured to grip a keeper.
11. The sliding door unit of claim 10 , wherein the latch is configured to fit within an aperture suitable for a cylindrical deadbolt.
12. The sliding door unit of claim 10 , wherein the latch is operable by rotation of a thumb-turn or key cylinder.
13. The sliding door unit of claim 10 , further comprising the keeper mounted to the mounting frame, the keeper comprising a keeper projection configured to be grasped by the latch.
14. The sliding door unit of claim 13 , wherein the keeper further comprises an alignment projection spaced from the keeper projection for aligning the active door panel with the mounting frame.
15. The sliding door unit of claim 14 , wherein the keeper is a two-piece construction such that a distance between the keeper projection and the alignment projection is adjustable.
16. The sliding door unit of claim 1 , further comprising a cylindrical lock actuation mechanism, and at least one of a door knob and a handle lever.
17. A sliding door unit comprising:
a mounting frame; and
an active door panel mounted in and capable of sliding relative to the mounting frame, the active door panel suitable for use as a hinged door panel, wherein the active door panel has a face including a panel portion and a glazing portion,
wherein the glazing portion comprises less than 65% of a surface area of the face, and the panel portion includes a pair of bores extending perpendicular to the face adjacent to a first side edge of the active door panel,
wherein a pair of apertures extend from the first side edge into communication with the pair of bores respectively.
18. The sliding door unit of claim 17 , further comprising a latch mounted within a first aperture of the pair of apertures and an adaptor mounted within a second aperture of the pair of apertures, wherein the latch is configured to selectively prevent sliding movement between the active door panel and the mounting frame, and wherein the adaptor is engageable with a keeper mounted to the mounting frame to align the active door panel with the mounting frame.
19. An active door panel for a sliding door unit, comprising:
a face including a panel portion and a glazing portion,
a pair of bores extending perpendicular to the face adjacent to a first side edge of the active door panel, each bore of the pair of bores configured to receive a handle set common to hinged entryway doors,
a pair of apertures extend from the first side edge into communication with the pair of bores respectively,
a mortise groove adjacent to each corner of the face; and
a guide roller assembly disposed within each mortise groove,
wherein the guide roller assembly is configured to permit sliding between the active door panel and a mounting frame, and
wherein the glazing portion comprises less than 65% of a surface area of the face.
20. The active door panel of claim 19 further comprising a latch disposed within an aperture of the pair of apertures, the latch configured to selectively prevent sliding movement between the active door panel and the mounting frame, the latch comprising:
at least one pair of pawls configured to grip a keeper.
