Sidelite Adapter (for High Dam thresholds, 10-36″ width)

Sidelite adapter to convert our high-dam thresholds for use in sidelite panels. Adapter (also known as a seat, spacer, or riser) replaces the threshold rail and supports and seals the sidelite panel which rests on top. Most common sizes are 10″ (for a 9 7/8″ panel), 12″ (for a 11 7/8″ panel) and 14″ (for a 13 7/8″ panel). In general, we recommend the riser be 1/8″ larger than the true width of the panel.
