Using the provided shop drawings, mark the center line from wall indicated in the shop drawings as “WALL TO CENTER OF STRINGER”

Next use the same shop drawings to mark out the top of your header plate - This measurement will be called out either from the upper subfloor or finished floor down to top of header plate

Line up the Header Plate Cover with the mark you made

Trace out the hole pattern of the plate onto the header

Using an 11/64" drill bit, predrill directly in the center of the center slot you outlined in STEP 1

If your FLIGHT system has LED lighting and the shop drawings indicate that the power is to be run from the lower floor up to the LED Driver inside the stringer tube, then locate and place the foot plate in the called out location in your shop drawings

Mark and drill out one of the larger holes in the center of the plate and pull Romex through from below

Bring the stringer into the environment to unpack

Look for the “Header” and “Footer” labels marked on the packaging

Unpack the stringer and set it on saw horses

It may be necessary to use a 1/2"-13 Tap to clear any extra powder coat from the treads of the holes before proceeding to the next steps

Use the 1/2" x 2" Flathead Bolts to attach the Footer Plate to the stringer

Torque to 70 lb-ft following the pattern above

Use the 1/2" x 2" Flathead Bolts to attach the Header Plate to the stringer

Torque to 70 lb-ft following the pattern above

With the help of others, flip the stringer on to the opposite side (FIG. A)

It may be necessary to use a 1/2"-13 Tap to clear any extra powder coat from the treads of the holes before proceeding to the next steps (FIG. B)

Place all but the first and last tread brackets on to the stringer lining up the 2 small holes on the inside of the brackets (FIG. A)

Secure the tread brackets using the provided clips (FIG. B)

Ensure each bracket is aligned and square with the stringer tube (FIG. C)

Thread the 1/2" x 1" flange bolts through the tread bracket and into the stringer in the marked order, until they are finger tight - Torque to 70 lb-ft following the pattern above (FIG. D)

Stringer Reveal: When the Header Plate extends below the header, and the hardware that holds the plate to the stringer would be visible after installation

This will be indicated in your shop drawings

Secure the provided Header Plate Cover to the Header

Plate using either tape or silicon and a clamp and let dry

Lift the stringer into place, lining up the hole

We recommend using either a pulley system or a Come Along Winch and brace material to hold the stringer in place while fastening

Fasten the 3/8" x 5" Lag through the middle slotted hole in the header plate to hold the stringer in place

While there are many styles of concrete header, the most common is a concrete deck pan with an I-Beam as support and steel plating welded on for backing

Secure our header plate with the through bolt hardware of your choice

Place a level on to one of the tread brackets about half way up the stringer

Ensure the tread bracket(s) are level left to right and front to back

Optional: Use multiple levels for increased accuracy

If not level left to right, shim the footer plate to adjust

Cut the excess shim away

Install the top tread bracket using the hardware and the process found in STEPS 8 & 9

Install the bottom tread bracket using the same hardware as you did on the top tread but only finger tighten the bolts as this tread bracket will most likely have to be removed in a later step

Locate the top and bottom treads and place them on the top and bottom tread brackets

Ensure that the bottom and top rise measurements are within 3/16" of the Tread Rise measurement found on the Customer Elevation page of the shop drawings

If the rise from the top tread to the upper floor is outside of 3/16" of the prescribed rise, loosen the center lag and adjust the header plate up or down as needed

Once it is where it needs to be, tighten the lag screw

Recheck that the tread brackets are level - see STEP 13

If the rise from the lower floor to the first tread is short by more than 3/16", shim the foot plate by the needed amount in order to raise the system up

If the rise from the lower floor to the first tread is more than 3/16" from the prescribed measurement, you will need to contact your Viewrail Project Engineer

If the stair system will be close to a wall, it is a good idea to check for a consistent distance between the stringer and the wall

Check at multiple spots along the stringer and wall

It may be necessary to remove the bottom tread bracket in order to accomplish the following steps

Select one of the holes in the center front row of the foot plate and drill a pilot hole using an 11/64" drill bit

Fasten the foot plate using a 3/8" x 5" Lag until snug

Predrill the remaining holes on the foot plate

Fasten the remaining hardware into the foot plate

Replace the bottom tread bracket, using the provided hardware - Torque to 70 lb-ft

At this point you can predrill the remaining holes on the header plate: Lag Bolts - Predrill utilizing a 11/64" drill bit Through Bolts - Predrill utilizing a 1/2" drill bit

Fasten the remaining hardware into the header plate

It may be necessary to remove the bottom tread bracket in order to accomplish the following steps

Drill a pilot hole in one of the center front row holes of the foot plate - Refer to the wedge anchor manufacturer’s documentation for the concrete bit diameter to use

Insert a concrete wedge anchor and torque to 50 lb-ft - Tapcons can be used as well

Predrill the remaining holes on the foot plate

Fasten the remaining hardware into the foot plate - Torque to 50 lb-ft

Replace the bottom tread bracket, using the provided hardware - Torque to 70 lb-ft

At this point you can predrill the remaining holes on the header plate

Fasten the remaining hardware into the header plate
