DETERMINING INSTALLATION DIMENSIONS
To determine the installation dimensions:
1.
Determine the smallest A dimension your vehicle allows. (Distance from top of floor to bottom of chassis plus
1-5/8”)
2.
Using the table below that corresponds to your gate’s arm length, verify that your vehicle is compatible with the max
sill depth, mount tube clearance and max unladen bed height for that A dimension.
3.
If necessary, increase the A dimension until the corresponding max sill depth, mount tube clearance and max unladen
bed height for that A dimension are compatible with your vehicle.
4.
Very acceptable ground clearance: Ground Clearance = Bed Height – A Dim – 10.25”
NOTE: Minimum allowable bed height is dependent solely on the required ground clearance.
Additional mounting configurations and dimensions may be available by contacting the Waltco Engineering
Department.
Important!
Do not exceed the maximum listed bed height for the A dimension used. This can cause damage to
the liftgate and improper proper operation of the liftgate.
