Question

What is the Commercial Hardware QMS/QME100?

Answer

The QMS/QME100 is a grade 1 mortise lever set. The QMS100 has a sectional trim whereas the QME100 is equipped with an escutcheon trim. There is no other difference between the two locks. Aesthetics is the major reason for choosing one trim over the other. The QMS/QME100 comes standard with a lost motion chassis that provides resistance to internal damage caused by physical force to the lever. Its thru-bolt design and heavy –duty spring tension provides longer performance life and prevents lever droop.
