Review the Parts Lists on Pages 6 and 7 to become familiar with the different components of your LB20.
Be sure all items were included before beginning assembly.
IMPORTANT: Installation of the LB20 will vary depending on what type of vehicle you have and how you
have it set up. Due to variables in different vehicles, the fit of the LB20 should be evaluated before beginning
installation. Some vehicles with a spare tire winch hoist will have a crank insert location in the rear of
the vehicle. Do not mount the ramp plate over this feature unless losing access to it is acceptable in
your application.
A. The LB20 Ramp is shipped partially assembled. Complete the assembly of the LB20 before beginning
installation. (See Page 3 for Latch Bracket assembly details, and Page 4 for Lift Assist assembly details.)
B. Before starting installation, place the LB20 in position and check all clearance issues. Be sure there is
adequate clearance between the LB20 and the van components (doors, door opening, etc.) Remember:
You will need access to both the ramp handle and the lever assisted latch if so equipped.
C. Once positioned, mark the 4 slots to be used for mounting the ramp as indicated in FIG. 1.For ProMaster
and Transit vans see FIG. 2. Set aside the ramp and the mount plate. Important: Before drilling,
double check that these holes are accessible and will not damage important van components.
Check under van to ensure no damage will occur in that area.
D. Drill four 29/64” holes.
E. Bolt the Ramp Mount Plate into place using the supplied 7/16” x 1 1/2” hex bolts, 7/16” flat washers, and
7/16” hex nuts
F. Confirm smooth operation and clearances.
