HRX-812 INSTALLATION PROCEDURE
1. Choose appropriate elevation. (See appendix A1, A2, OR A3)
2. The first step of the installation process is to hang two “Down-Leg” brackets (
not
provided
) for each section of rail from the ceiling structure down to where the top of the
rail height will be. The material for the brackets and down legs is typically Unistrut
Telespar or similar load bearing channel.
(Check with architectural drawings to see if
any are specified.)
The down leg (
not provided
) should be 1 ¾” x 1 ¾” O.D. square
channel and will slide into Harvey’s Hanger Brackets (HRX-HGRBRKT) that mount
directly to the top of the rail. It is important to make certain that the hanging brackets do
not align with the rail joints which will be every 12’. It is imperative to the success of the
installation to make certain that the hanging brackets are all hung straight, level and
vertically true in order to ensure proper alignment of the rail sections. It is recommended
that a stringer or laser level be used to ensure the rail is level and straight.
3. Attach the Hanger Brackets (HRX-HGRBRKT) to the down legs (not supplied,
recommend Unistrut). (See appendix B).
4. Lay out all the sections of rail, end to end with the opening facing up on the ground
below where it is to be hung. The rail connection brackets (HRX-CKT) have already
been attached to the rail at the factory (See appendix C). The brackets should be attached
to both ends of each section, except for the two extreme ends which will consist of only
one side having connection brackets.
5. The connection brackets will need to be moved to the end of the rail. Loosen the
5/16"-18 x ½” bolts and slide the bracket along the slot until the edge of the bracket is
1/4" away from the edge of the rail. Tighten fully and repeat on opposite side.
6. Affix the alignment pins with the provided adhesive on the bottom of the rail. Apply
an ample amount of the provided adhesive to both the pins and the round slots on the
bottom of the rail (See appendix C). Slide the pins in half way while simultaneously
rotating them to ensure even coverage. Allow adhesive to set up. (Heat will speed drying
time.)
NOTE: Decide which end section you are going to hang first and start at the end of that
section that will be connected to another section. Alignment pins will be placed in the
similar end of each section, so that there are one set of alignment pins per joint.
7. Flip over all sections of the rail.
