Abstract: The present disclosure includes a system and article of manufacture comprising a universal sliding door frame. The frame may comprise a first track having a first interface and a second track having a second interface. The second interface may slidably couple to the first interface. In addition, the second interface may be orthogonally inseparable from the first interface. In an embodiment, the frame may comprise a spacer that separates the first track from the second track and slidably couples to the first track via the first interface and the second track via second interface. The spacer may, in addition, be orthogonally inseparable from the first and/or second tracks.
