4. Make sure both brackets are slid all the way up against the
plastic rail caps. Using the provided 5/32” allen wrench,
tighten the 6 screws on both Tower brackets. See Figures C
and D.
5. Install the Tower frame onto the brackets.
a. Orient the Tower frame so that the large threaded holes at
the bottom face away from the carriage.
b. Lift the Tower frame over the brackets and lower it
around them so it rests on the ledge at the bottom of the
brackets. See Figure E.
c. Slide the frame toward the bracket until it is flush.
d. With one arm or an assistant holding the Tower frame
upright and in position, start threading the 4 large knobs
into the Tower frame. You may have to push on the frame
to get it into position with the knob, and if one is giving
you trouble, just move onto the others and come back
to it.
IMPORTANT NOTE: Get all four knobs started 3-4 turns
into the Tower frame before tightening any of them. It is
also critical that the Tower is parallel and flush against
the bracket with the knobs. You may have to push/pull/
twist the leg of the Tower to make it line up.
e. Once all four knobs are started tighten them one by one.
6. Install the adjustable pulleys by assembling the components
as shown in Figure F with the pulley on the inside of the
frame. Tighten the knob when the eyebolt is horizontal as
shown in Figure F. Repeat on the other side.
7. Install the lower spring mounts in the head end of the frame
with the long screw and the 5/32” allen wrench. Tighten the
screw with the eyebolt oriented vertically as shown in Figure G.
8. Rethread your ropes through the new riser pulleys.
