CENTER STOP ASSEMBLY
Fasten one half of the guide with 3/8" lag bolts. Locate the "Z" stop on the center lag of the unfastened half as shown in Fig. 24.

Secure half with lags. Finally attach "L" hold down to "Z" stop with 3/8" carriage bolt as shown in Fig. 25.

After the guide is in place, additional adjustment is possible through the vertical adjustment on the door trolleys. This adjustment should be used only after the center guide is rigidly in place.
