Place 4” block of wood on top of pivot cap.
Keep 2 wedges handy. This block MUST NOT
BE REMOVED until telestrut, winch and cable
are installed and fully secured. Severe injury
may result if center tube pivots without
block or telestrut/winch restraining or
controlling it!
Lower center tube onto pivot cap. Line up holes
in the center tube lugs with bore in the cap and
insert 13” bolt. Note: 1 washer should be under
nyloc nut.
Drive wedges from either side of center
tube between block of wood and bottom of
center tube. This will further stabilize
center tube for the following steps.
Install 2 cross pieces. Make sure small
socket head bolts reference either side of
center tube end plates. Leave 5/8” x 6”
clamp bolts just slightly less than tight to
facilitate installing longitudinals in next
step.
Make sure your wedges are snug! Install
longitudinals (2 ½”
sq. washer on top,
3” sq. washer on
bottom) with 8”
bolts. When both
longitudinals are
installed, tighten the
cross piece clamp bolts and the 4 cross
piece/longitudinal connection bolts.
