Notes About This CatalogWherever escalator types are shown, the standard escalator of that type is

assumed unless otherwise specified. For example, “J” means J escalators, whereas “J Escal-Aire®” is used to indicated that specific sub-type.

Most measurements are provided in both Imperial units (for the United States) and metric units (for Canada, Mexico, etc.). If only one form of a measurement is provided, assume Imperial units (generally inches) unless otherwise stated.

Most Imperial measurements are rounded to the nearest tenth or hundredth of an inch and most metric measurements are rounded to the nearest millimeter.

The size of early escalators (Imperial/pre-Metric) is obtained by measuring between the balustrade panels or the glass panels. On Otis units, the step width is 8 inches narrower than the escalator width. For example:

• A32R is32inchesbetweenthebalustradepanelsandhas24-inchwide steps.

• A40UBor40Jescalatoris40inchesbetweenthebalustradepanelsandhas32-inchwidesteps.

• A48Rescalatormeasures48inchesbetweenthebalustradepanelsandhas40-inchwidesteps.

Escalators are designated by either a metric measurement, an imperial measurement, or both. This picture shows how those measurements are determined. Note that the imperial measurement (shown top) is from the left balustrade panel to the right balustrade panel. The metric measurement, however, indicates the nominal step width. This explains why thetwomeasurementsdonotconvertproperlybetweensystems(whya48-inchescalatorisalsocalleda1000mmescalator).Toavoiderrors,measurethesteporpalletwidthandprovide that measurement to UNITEC.

Ever wonder why a 48RB escalator has only a 40-in. wide step?
