3. Insert the bolt head into the slot and add a ½" lock washer and
thread a ½" nut onto the end of the bolt.
Inverted or Upside-Down Installation – Bottom-mounted
Couplers, V-nose Trailers
Install the assembly upside-down if you have a trailer with a bottom-
mount coupler, V-shaped nose, or any other obstacle that prevents
them from being installed right-side up.
1. Slide the assembly up around the frame until the bolt hits the
bottom of the trailer frame with the mounting bolts facing out.
2. Insert the second ½" x 4" bolt through the open hole closest to the
top of the trailer frame. (Figure 10)
3. Insert the bolt head into the slot and add a ½" lock washer and
thread a ½" nut onto the end of the bolt.
No Gaps
For either typical or upside-down installation there should not be a
gap between the trailer frame and the link plate bolts either above or
below the trailer frame. Move electrical or propane lines if necessary.
(Figures 11)
Pinch the link plates flat against the sides of the trailer frame, and
hand tighten both nuts. (Figure 12, 13)
When the nuts have been tightened by hand and both link plates are
held flat against the frame, use a torque wrench to tighten all the link
plate bolts to 65 ft-lb.
L-bracket Installation
Place the L-bracket onto the outside link plate with the bolts in the
two middle holes. Thread on the nylock nuts and hand tighten them
until the L-brackets are held firmly in place. (Figures 14, 15)
for top-mounted coupler.
