ABSTRACT:
A fixed sill includes a pair of lower, outwardly extending fixed sill flanges. A generally vertical longitudinally extending support plate is integrally connected to each fixed sill flange on each side of the fixed sill. A sliding sill support is rigidly connected to each support plate. The sliding sill support includes a horizontal inwardly extending portion that also extends longitudinally inboard. The sliding sill support is located slightly below the fixed sill flange. A pair of low friction wear plates are adopted to be slipped in place upon each sliding sill support. The low friction wear plates include horizontal body portions on each side of the fixed sill upon which the sliding sill rides in moving back and forth. Each wear plate includes "U" shaped end portions which wrap around in the inner and outer ends of the sliding sill support. The wear plate is made of resilient material having a low coefficient of friction with steel and good strength in compression to withstand the load of the sliding sill.
