### Things to Know Before You Get Started

* Before you get started, review your print set, specifically reviewing the steel exploded assembly print(s) and the wood exploded assembly print(s)
* Read over the provided material prior to the start of your installation
* This is, at minimum, a two person job
* Viewrail Glass systems and fittings are designed to have a 1" gap between panels of glass

### Install Steps

<figure><img src="/files/ygoWgLQ52F01Zy1wAm1T" alt=""><figcaption></figcaption></figure>

* Per the provided plans, locate the called out Finished Floor to the top of Plywood Header Template measurement & mark where the template will be placed
* Hold the Plywood Template in place, drive 5 wood screws to secure the template to the header

*Note on Blocking: Plywood Templates must be mounted directly to either double LVL or Triple 2x. If the wall has a compressible surface, e.g. drywall, it must be cut away before hand.*
{% endcolumn %}

* If finished flooring is not yet installed, add subfloor material equal to the finished floor thickness (X) beneath\
  the stringer feet and under tread pans 1 and 2

*Note: X = thickness of the finished floor*
{% endcolumn %}

<figure><img src="/files/M8g6DP67F96dIRa3zYRI" alt=""><figcaption></figcaption></figure>

* Line up the top of the Plywood Stringer Template with the top of the Plywood Header Template
* While it is held in place, secure it to the wall backing using wood screws - it is not necessary to populate every hole, just enough to secure it for now

*Note on Blocking: Plywood Templates must be mounted directly to either double LVL or Triple 2x. If the wall has a compressible surface, e.g. drywall, it must be cut away before hand.*

* DO NOT tighten bolts all the way down in this step

*Notes: On stringers that are not butted up to a wall, it will be easier to insert set screws from the outside. Due to the powder-coating process, you may need to run a 3/8"-16 bolt through the threaded holes on the stringers before*\
*mounting the tread pan, to clear the threads.*

For orders where the steel arrives first, and is installed before the finished wood & glass arrives on site, cut 2x12 lumber to the correct tread width and mount them onto each tread pan. Secure it with wood screws from underneath the tread pans. This prevents slips since moisture or debris on bare tread pans can be hazardous.

At this point, the Steel First portion of the installation is complete. This stair system will act as a sturdy set of temporary stairs for the remainder of the overall project. The following steps of this instruction manual, will be used once you have received the finished wood treads & glass panels and are ready to install them to finish the job.

*Note: It is suggested to attach some 2x4’s to the top of the panels to create a more ridged structure. This will act as a safety railing during the remainder of the overall project*
