TRACK ASSEMBLY

1. Assemble both tracks by installing the track spacers (Figure 2).

2. Install the idler assemblies onto the wall end of the tracks. One

idler assembly is set up with a coupling sprocket on each end,
and the other idler is set up with only one coupling sprocket.

3. Slide the slider assembly into both tracks from the open end.

Be sure that the take-up bolt is facing the open end of the track.

4. Install the idler roller assemblies onto the open end of the

tracks.

5. Install the chain, use the take-up bolt to adjust the chain

tension to allow about 3" sag in the center (remove links
if necessary).

6. Determine which side of the door the operator will be mounted

on and install the track with the double idler on that side at the
center of the opening.

7. Install the track assembly with the single idler on the other side

of the center of the opening. Brace the tracks appropriately.

CONNECT TRACKS

1. Determine the length of the shaft needed to couple the two

tracks together and cut the shaft provided to that length. Slide
two bearing assemblies on the end of the shaft.

2. Install a 48B14 sprocket on each end of the shaft using the 

(2) 1/4" x 1-1/2" roll pin provided (Figure 1).

3. Use a tape measure to set the slider assemblies the same

distance from the wall.

4. Couple the shaft between the two idler assemblies by butting

the 14 tooth sprockets together and connect with a #40 chain
and master link (Figure 2).
