1. Cut two vertical rails to required heights, allowing 3/4" to 1" overlap of the door opening at the top. Verticals should be 1" shorter than the overall door height to allow for the bottom rail.

2. Cut the required number of girts to correct widths. Suggest doors overlap jambs 1 1/2" on each side: 2 1/2" it Combo No. 190500 Keeper-Stoppers are used.
Recommended girt spacing is 24" on centers. Note: Overall door width will be 1 1/2" wider than girts. due to box extrusions in the vertical rails (Figure 6).

3. Construct top rail by sandwiching together one 2" x 6" and one 2" x 4" with a 1/2"
plywood spacer, as shown in Figure 7. Cut to same width as girts. Drill the 2" x 6" for mounting trolley hangers.

4. Lay the vertical rails with J-trim facing down on a flat, even surface and insert all girts into the verticals, as shown in Figure 1. Insert the top rail so that the 2" x 6". which is drilled for mounting the trolley hangers, will be on the inside of the door. Attach the vertical rails to the girts with
one 3" nail at each joint.

5. Diagonally square the door frame, as shown in Figure 2. Adjust as needed and secure with a second 3" nail at each joint.
6. Turn frame over, re-square, and secure the front side of the verticals to the girts with one 3" nail at each joint. Completed
assembly will have two 3" nails in the back and one 3" nail in the front at each joint.

7. Attach Combo No. 153500 Bottorn Rail to bottom girt, using nails or screws in all four fastener holes provided in each bottom rail mounting bracket (Figure 9). Note: Bottom Rail may be spliced.

8. Apply skin, trolley hangers. door hard-ware and optional weather stripping (Figure 4). Hang door(s) on building, as explained on the last page.

9. Install bottom guide rail as explained on the last page.

10. For double or split slide doors. attach optional SDR1635BC Box Vertical Closure.

1. Cut two vertical rails to required heights, allowing 3/4" to 1" overlap of the door opening at the top. Verticals should be 2" shorter than the overall door height to allow for the bottom rail.

2. Cut required number of girls and bottom rail to correct widths. Suggest doors overlap jambs 1 1/2" on each side; 2-1/2" if Combo No. 190500 Keeper-Stoppers are used. Recommended girt spacing is 24" to 30" on centers

Note: Overall door width will be 1 1/2" wider than girts. due to
box extrusions in vertical rails (Figure 6).

3. Construct top rail by using two girts, one on top of the other (Figure 8), and drill for
mounting trolley hangers. Note: Locate trolley mounting holes 3/4" in from rear of lop rail, and attach Combo No. 199000 Trolley Support Plates under lower top rail.

4. Lay the vertical rails with J-trim facing down on a flat, even surface and insert top
rail, girts and bottom rail into the verticals, as shown in Figure 1. Face the bottom rail
stiffener downward to fit against the J-trim on the verticals (Figure 5).

5. Attach the vertical rails to the top rail, girts and bottom rail using one 1" TEK screw at each joint.

6. Diagonally square the door frame, as shown in Figure 2. Adjust as needed and insert a second 1 " TEK screw at each joint.

7. Turn frame over, re-square and secure the front of the verticals to the girts with one 1 " TEK screw at each joint. Completed assembly will have two 1" TEK screws in back and one 1 " TEK screw in front at each joint. Note: If the flat of the steel skin is to be inserted into the small J-trim (Figure 4).
attachment of the front screws should be delayed until after the skin is installed.

8. Apply skin. trolley hangers, door hard-ware and optional weather stripping (Figure 4). Hang door(s) on building, as
explained on the last page.

9. Install the bottom guide rail. as explained on the last page.

10. For double or split slide doors, attach optional No. SDR1635BC Box Vertical Closure Rail.
