Attach support tube bracket which are included in the MRRC (CONNECTOR
– RAMP TO RAMP) to the center saddle bracket (previously installed) using
3/8″ nylon insert lock nuts and 3/8″ washers (FIG. 3.5).
3.3.2.
Level the support tube brackets (FIG. 3.6), then secure and tighten the 3/8″

3.3.4.
Locate MSTSxxPR (FEET AND SUPPORT TUBE PAIRS). Place a foot under
each support tube bracket, then slide the support tube through the support
tube bracket and into the foot. Make sure the support tube is fully engaged
into the foot and that the foot is oriented so it extends under the ramp. Tighten
the thumb screw on each foot securely (FIG. 3.7).
NOTE:
If installing on soft
soil it may be necessary to set the foot on a concrete pad.
3.3.5.
Adjust the support tubes one at a time.
3.3.5.1.
Raise the ramp sections (at the center saddle bracket) to take
any sag out of the ramp run, then tighten the two bolts in each
support tube bracket.
3.3.5.2.
Place a plug into the top of each support tube (FIG. 3.7).
NOTE:
Adjusting sections can be accomplished by having someone
sight down the ramp while another person adjusts the ramp
height.
IMPORTANT:
Ensure that the ramp sections are parallel
to each other. If they are not, it may be difficult to install the
handrails (FIG. 3.8).
3.3.6.
Double check that all bolts are tight, the support tubes are plumb, and the
ramp sections are aligned parallel to one another.
