turns and use a 13 mm socket wrench to tighten to
appropriate torque.
Note: Do not place two 1 in 1 rail splices next to each
other.

4. Use shim kit to level the height of the rail on the
roof. Place shim between rail and standard slider top
bracket. Slide the shim into the bolt so that it is fully
engaged.
Note: There are two types of leveling shims, 0.1"
(AK113) and 0.4" (AK114). You will need to use bolts of
different lengths, according to the total thickness of
the shims. Refer to the following table.
