Balanced doors are lighter on everything: the opener, the hinges, the rollers and the arms of anyone who has to lift them in a power cut. The spring and cable work here is how that balance is set and kept.

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.
