FINAL FRAME CHECK
1. Return to frame connections and verify bolts are tight.
2. Verify each purlin splice is secured with a Tek screw.
3. Verify each purlin is secured to pipe strap and cross
connector and that each cross connector and pipe
strap is secured to rafter. See diagram below.
4. Inspect frame for sharp areas that could damage
cover. If found, file smooth and cover with layers of
duct tape to protect cover.
5. Verify all bolts are positioned with heads to the
outside of frame. Tape bolts, rafter joints, and cables
before
installing cover.
6. Verify cables wrapped around rafters at top of frame
are covered with layers of duct tape or material to
protect cover when installed.

one another below
the same rafter
to best stretch and
secure main cover.

Photo shows straps and cover already installed,
these items are installed later in the instructions.
Additional materials required to secure ratchets to
concrete are not included and must be purchased by
customer. Materials and frame shown in the following
diagrams may differ from actual items.
Consult the
Attaching Rafter Feet to Concrete
section on
page 8 to determine anchor bolt size that best applies.
1. Determine where to attach first ratchet and drill
mounting hole according to anchor bolt size.
NOTE:
Hole needs to be deep enough so anchor bolt
will not interfere with ratchet operation.
2. With ratchet in open position, insert anchor bolt
through ratchet hole and into mounting hole. Firmly
tap with a hammer to secure wedge anchor into
concrete.
NOTE:
Depending on wedge anchor bolt, verify that
washer and nut are attached
before
driving anchor
bolt. Striking bolt may cause thread damage and
prevent the nut installation.
3. Tighten nut and test ratchet operation. Cut excess if
needed.
4. Repeat for each ratchet.
ATTACHING RATCHETS TO CONCRETE PONY WALL
4. Measure approximately 24" down from top of pony
wall or support posts and attach ratchet.
Install ratchets immediately across from each other
below the same rafter.
