7. Install U-Tubes
Locate the U-Tubes, two (2) 5/16” X 2” Bolt assemblies (LL), twelve (12) 5/16” X 4” Bolt assemblies (EE), sixteen
(16) 5/16” X 1” Bolts (QQ),and sixteen (16) 5/16” Flat washers (FF).
Two U-Tubes are unique from the other six. These two have custom holes that are meant to be secured at
the front (3 holes) and the rear (5 holes) of the trailer. The remaining U-Tubes are all identical and can be
used in any order.
Remove the bolts in the front holes (nearest to the hitch) in the Frame Tubes. Place U-Tube with (3-Holes) over these
holes and secure it with the bolts (used in step 3.) Place U-Tube with (5-Holes) over the rear holes and use the two
(2) 5/16” X 1-3/4” Bolts (DD) to hold it to the Frame Tubes.
Use the twelve (12) 5/16” X 4” Bolts (EE) and use the bolts to hold the remaining U-Tubes to the Frame Tubes. Do
not install the washers and lock nuts at this time.
Important: All bolts will fit properly if the undercarriage is square. The undercarriage has a loose fit to allow for adjustment
at this stage if it is necessary.

8. Install Side Panels and Floor Panels
Once the U-Tubes are mounted on the Frame Assembly in the proper order, place a Pin Nut into the openings in the
top of each U-Tube. Align the slot in the Pin Nut with the side of the U-Tube so that the side of the tube will go into
the nut when it is tightened. If necessary, lightly tap the Pin Nut into place with a plastic hammer to avoid damaging
the Pin Nut.
Locate the 84” x 20” side panels and position the 1” panel return on top of the U-Tubes, with the 20” portion of panel
resting on the inside of the U-Tubes.
Place the two C-Channels on top of U-Tubes/panel profile and install the sixteen (16) bolts and hardware from the
Pin Nut assemblies (5/16” X 1” Bolts, Stainless Steel Flat Washers, Lock Washers). Thread the bolts through the
C-Channels, side panels and into the Pin Nuts.
Secure all hardware for Assembly Fit (Tighten later).

IMPORTANT:
Correct placement of side panels means 4 square
holes (fender mount holes) will be above axle.
