1. Make sure the corner friction block cover plate is on top of the UHMW (plastic)
corner friction block and a 3/8 internal star washer is between the friction block and
the friction block mounting flange of the tower. This washer is necessary to insure a
grip between the friction block and the metal flange of the tower.
2. Use 1/8” spacers to center the inside tower in the middle of the outside tower.
SEE ILLUSTRATION.
3. Using a .010” shim and .020” shim for spacers, place a .010” shim between the
friction block and the inner tower section sides. SEE ILLUSTRATION.
4. Make sure the inner tower is against the 3/8” thick UHMW blocks mounted
inside the outer tower and use the .020” shim to set the friction block distance from
the inner tower section. SEE ILLUSTRATION.
5. Tighten the ¼-20 nuts. And continue to set all corner friction blocks on all sec-
tions using this procedure.
