VEVOR Bypass Door Hardware, 1.83 m Heavy Duty Bypass Sliding Door Hardware Kit, Sturdy Aluminum Alloy Sliding Closet Door Hardware Set for 2 Door System, Fit Door Thickness 35-45 mm, Easy to Install

Yes — 927 mm is just the maximum door width per panel. Narrower doors can be used (or the 1.83 m track can be cut to fit). Total Thickness (2 Doors + Track): Approx. 90 mm – 105 mm (3.5" – 4.1"), depending on door panel thickness (fits standard 35 mm – 45 mm thick doors).

We do not recommend splicing tracks, as it is difficult to install them evenly and will affect their use.
