7.1 INSTALLING CEMENT BLOCKS & BASE
Each leg group requires its own concrete base; this solid foundation prevents movement in case of
heavy winds.
Step1: Pour concrete bases for each leg group according to the figure below. The bases should be
51.2 in. (1300 mm) apart, center to center.
Step 2: The detailed top-down view of a concrete base, shown below, indicates the mounting
location, orientation, and dimensions for the leg group main base bracket. After the concrete bases
have dried sufficiently, use the main base bracket as a template to mark the correct hole locations on
the top of each base. Drill four (4) 0.6 in. (14 mm) diameter by 3 in. (75 mm) deep holes. Install the
four (4) M10x100mm concrete expansion bolts into the holes with the flat washer, spring washer,
and hex nut.
Step 3: Install a leg group on top of each
base by placing the main base bracket over
the four expansion bolts installed in step 2.
Install a flat washer, spring washer, and 17
mm nut on each anchor bolt and torque the
17 mm nuts to 230 in-lbs. (26Nm).
