4.5 Assemble the Legs and Rail
1. Support Legs
2. Unistrut bar clamps
3. Side Braces
4. Rail
a. If you are attaching the Support Legs (1) to the top or bottom
of a steel beam, use Unistrut bar clamps (2). To attach to the
top or bottom of a bar joist, use a thru bolt in the slot of the
bar joist.
b. Mount the Support Leg to the roof or to beams. The first leg
will be approximately 3 to 4 ft (0,9 to 1,2 m) from the end of
the track or rail. Leg assemblies will need to be placed every
10 to 12 ft. and braced side to side using the appropriate
length side brace kit.
Note: Longer braces can be made out of ¾ in. (19 mm) EMT
conduit and attached to the leg using a Plymovent 8130-1011
leg/brace mounting kit. You should have at least one long
brace running front to back.
c. To calculate the leg length, determine the mounting height of
the rail, then subtract that dimension from the bottom of the
strut. Cut the aluminum square tube to this length.
Center a triangular foot and drill 2- 13/32 in. holes to attach
foot. Repeat for the bottom foot positioned perpendicular to
the rail (4). Attach the leg assembly to the strut on ceiling
using 3/8 in. strut hardware. Attach the side brace kit (3).
For multiple legs, turn the side braces perpendicular to the rail
and install one long front to back brace. Repeat for each leg
assembly.
d. To splice two rails, position the rail sections on saw horses.
Insert and center a splice plate (6) inside the rail (5), clamp in
place with a C-Grip and drill 2- 5/16 in. (8 mm) holes on top 2
in. from the joint and 4 in. apart.
On both sides, drill the first 5/16 in. (8 mm) hole 2.5 in. (63,5
mm) from the top of the rail and 1 in. from the joint. Drill the
second 5/16 in. (8 mm) hole 2.5 in. (63,5 mm) from the first
hole. Insert the bolts but leave them loose. Silicone the joint
and slide the other rail section onto the splice. Line up straight
in both directions and clamp. Drill the same holes on the
mating rail. Tighten the bolts in sequence - first tighten the
top 4 bolts, and then the remaining 8 bolts on the sides for a
total of 12 bolts.
