Fit the Rack

galvanized steel rack. The galvanized steel rack is usually used for the heavy duty gate.
A. Fit the plastic rack reinforced with steel
1. Start with gate in closed position
2. There are four sections of plastic rack which is one meter length, each section for standard package. (you
can order extra rack from dealer if necessary)
2. Put one end of rack section on the gear of opener as a temporary support.
Make rack level and mark the rack's mounting holes (four holes) on the gate.

be made even after it has been fixed. Please keep 1.0mm space between the rack and the gear to avoid the
weight of the gate leaf effect on the opener.
