• The recommended distance from the end of the rail to the
door(s) (6) can be found in the installation table on page 6.
WARNING!
Product may contain sharp edges. Use care when
servicing the unit, failure to do so could result in
minor personal injury.
ATTENTION
Based on the door height and distance from end of
the rail, a cantilever under the door may be required,
so that the vertical hanger leg does not obstruct the
door track. Typically, the cantilever is required once in
a back-in-system and twice on a
drive-through-system.

Splicing two rails
To splice two rails, position the rail sections on saw horses.
• Insert and center a splice plate 4 in. (100 mm) (2) inside the
rail, clamp in place with a C-Grip and drill 2 Ø 0.42 in. (10,5
mm) holes that are 2.6 in. (65 mm) apart on the top and on
both sides.
The splice is mounted together with 12 pcs of M10 x 25 mm
(0.42 in.) bolts.
*
• Use the upper v-groove to drill the holes in the rail and insert
the bolts but leave them loose (3).
• 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 bolts, and
then the remaining bolts on the sides.
*
Fastening material is included in the splice package.
ATTENTION
Make sure the spliced rails are straight and the rail
channels are lined up. This will ensure that the rubber
seal can be inserted properly.

Assemble the legs and the rail
• Support legs can be attached to the following:
- Steel beems - use unistrut bar clamps (1). To attach to the
top or bottom of a bar joist, use a thru bolt in the slot of the
bar joist.
- Drywall ceiling with wood framing - locate center of trusses,
cut strut to span 3 trusses, drill 1/4 in. pilot holes and
mount strut using 3/8 in. X 3 1/2 in. grade 5 lag bolts.
- Poured or Pre-Cast Concrete - use a stud or wedge type
concrete anchor usually a 3/8 in. X 3 in.
•
Mount the support leg to the roof or to beams. The first leg
should be 4 to 5 ft (1.2 to 1.5 m) from the end of the rail.
Leg assemblies will need to be placed every 10 to 12 ft. (3 to
3,6 m) and braced side to side using the appropriate length
(20, 30 or 72 in.) side brace kit.
Note: Longer braces can be made out of ¾ in. EMT conduit
and attached to the leg using the Plymovent leg/brace
mounting kit. You should have at least one long brace
running front to back.
• Fasten the top suspension upper bracket to the support leg.
Predrill 0.2 in (5 mm) and then 0.42 in. (10,5 mm) (3 and 4)
that align with the holes in the bracket. Position the bracket
on the leg so it is centered, then drill the third hole in the leg
(2). Add bolts and nuts but do not tighten, as you will need
to cut the support leg.
• Mount the the support leg to the roof or to the beams. To
calculate the leg length, determine the mounting height of
the rail, then subtract that dimension from the bottom of the
strut. Cut the support leg to this length.
• Side suspension: plummet the position of the supports and
attach the side suspensions to the rail. Center a triangular
foot and drill 2- 13/32 in. holes to attach the foot. Mount top
suspension lower bracket to the support leg without
tightening the bolts. Mount the support leg to the roof or to
beams. Attach the leg assembly to the strut on ceiling using
3/8 in. strut hardware. Attach the side brace kit (5).
• For multiple legs, turn the side braces perpendicular to the
rail and install one long front to back brace. Repeat for each
leg assembly.
