MOUNTING THE OPENER:
1. Getting started.
• Position assembled rail
on wall next to header
bracket
(Fig. 2-4).
– Place material on floor under power head to
protect from scratching. (A box, stool, or
similar device may be needed to clear a
torsion spring.)
NOTE: For header bracket pins locate Bag 2 from
Box 1.
2. Mounting the assembly.
• Attach rail to header bracket using clevis pin
and cotter pin.
• Support power head on step-ladder to prevent
interference with header mounted (torsion)
spring (Fig. 2-5).
NOTE: Before final attachment to ceiling, insure
that assembly is in proper alignment (Fig. 2-4).
NOTE: For nuts, bolts, and lag screws locate Bag
3 from Box 1.
• On finished ceilings, locate ceiling joists or
trusses using a stud finder or similar device.
Attach angle iron (not provided) to joists or
trusses through finish material using (provided)
lag screws (Fig. 2-6).
• On unfinished ceilings or open ceilings, straps
may attach directly to joists or trusses.
Depending on the garage construction, extra
framing material (not provided) which may be
required should be installed using appropriate
construction techniques (Fig. 2-6).
NOTE: Refer to your local building codes for
appropriate construction techniques.
• Attach mounting straps to ceiling using lag
bolts (Fig. 2-6).
