Counting hinges and measuring stems
The right replacement depends on numbers taken from your door, not from a catalogue. The wheel diameter is measured across its face: residential track takes a two-inch wheel, while commercial track can take a two-inch or a three-inch wheel depending on the system. The stem is measured from the wheel to its end, and the hinges at each end stile are counted, because a single hinge takes a four-inch stem while two hinges stacked together on a heavier door call for a seven- or ten-inch stem that reaches through both.
Stem diameter is confirmed too, since most doors built since the 1980s share one standard size but older doors may not. These measurements decide which set goes in.
