1. Place a support tube on one of
the two mounting holes in the
rain collector base.
2. Place a lock washer and a flat
washer onto one of the 7-3/4"
(19.7 cm) screws. Hold the
shelf so the support tube
screw hole is over the center
of the tube (see figures).
Insert the screw through
the shelf, the tube and the
base.
3. Hold a nut in the opening of
the hexagonal recess on the
underside of the base.
Turn the screw until the
assembly is loosely held
together.
4. Repeat steps 1–3 with the sec-
ond support tube and screw.

ensure that both tube-ends
are inside the circular
recesses in the shelf.
