Step 10Expansion Hardware
The Expansion Hardware consists of several sizes of galvanized pluming.
At the center of the Expansion Hardware is two reducer fittings:
A 1" to 3/4" reducer fitting -Main Reducer
A 1" to 1/2" reducer fitting - Minor Reducer
Both fittings are free to be rotated by hand to expand the beam to press against the side walls of the truck bed. The shoulder of the Main Reducer presses against the edge of the fence post to carry the load from the fitting to the beam.
As both reducer fittings are unthreaded the overall length of the beam increases.
(The expansion occurs between the 1/2" pipe and the Minor Reducer, and between the Main and Minor reducers)
The 3/4" fittings to the right of the Main Reducer is telescoped inside of the fence post and rotates with the Main reducer. Its purpose is to keep the Expansion Hardware aligned with the Beam.
