1. Select the location for the concrete base footing. Dig a 12” diameter hole that is a minimum of
48”deep. In areas where the normal frost line is below 48” it is advisable to dig
to the normal frost line. (Consult a local concrete contractor if there is any question.)
Reference ( Figure 1 )
2. Make sure that you have a broomstick or similar pole to vibrate air pockets out of concrete. The
12” diameter by 48” deep hole will require approximately 3.25 cubic ft. of 3000
PSI concrete (6 to 8 60# bags of premix concrete). You will need to adjust the amount depending on the
size of hole you prepared. Having the proper amount of concrete before you
start will ensure proper strength of the footing.
3. Mix concrete according to the directions on the bag. It is advantageous to have the mixture “wet”. This
will increase your working time and allow batches to mix in the hole. Pour the hole full to ground level.
Attach band clamp to bottom end of pole and insert pole into concrete while vibrating concrete to allow it
to surround the pole completely. The pole height from the ground should be 11 feet (see Figure 4 ).
4. Clean excess concrete from pole. Level the pole in the hole and allow the footing to cure for seven (7)
days. Only after the concrete has cured for seven days should you proceed.
5. Seven Days have passed. Secure the Extension Arm to the pole at a distance of 9’8” to the bottom of the
arm
(see Figure 4 ) to the playing surface with the 4-1/2” U-bolts (M), 1/2” Flat Washers (Q), 1/2” Lock
Washers (R), and 1/2” Hex Nuts (S). NOTE: Middle hole does not require a Flat Washer (Q)
(see Figure 2 ).
6. Assemble rim and backboard to the Backboard Mounting Bracket (A) using the hardware provided with
the rim. Slide the 4-1/2” Band Clamps (B) on to the Extension Arm and attach the Backboard Mounting
Bracket (A) assembly containing the backboard and rim to the end of the Extension Arm with 1/2” Square
Head Set Screws (O) as shown in (see Figure 2 ) making sure rim is level. Fasten Backboard Braces (N) to the
backboard with 7/16” x 2” Carriage Bolts (C), 7/16” Hex Nuts (J), 7/16” Flat Washers (K), 7/16” Lock
Washers (L), and to 4-1/2” Band Clamps (B) with 5/16” x 2” Carriage Bolts (G), and 5/16” Flange Nuts (H)
as shown in ( Figure 3 ).

1. Select the location for the concrete base footing. Dig a 12”
diameter hole that is 36”deep. In areas where the normal frost
line is below 36” it is advisable to dig to the normal frost line.
(Consult a local concrete contractor if there is any question.)
2. Make sure that you have a level and a broomstick or similar
pole to vibrate air pockets out of concrete. The 12” diameter
by 36” deep hole will require approximately 2.5 cubic ft. of
3000 PSI concrete (6 to 8 60# bags of premix concrete).
You will need to adjust the amount depending on the size of
hole you prepared. Having the proper amount of concrete
before you start will ensure proper strength of the footing.
3. Mix concrete according to the directions on the bag. It is advantageous to have the mixture “wet”. This
will increase your working time and allow batches to mix in the hole. Pour the hole full to ground level.
Attach 3-1/2” Band Clamp (B) with 5/16” x 2” Carriage Bolt (G), and 5/16” Flange Nut (H) to bottom
end of pole and insert pole into concrete while vibrating concrete to allow it to surround the pole
completely. The pole height from the ground to the bottom of the bend should be 9’ 8”. See Figure 1
and Figure 3 on the following page.
4. Clean excess concrete from pole. Level the pole in the hole and allow the footing to cure for seven (7)
days. Only after the concrete has cured for seven days should you proceed.
5. Seven days have passed. Slide the 3-1/2” Band Clamps on to the gooseneck portion of the pole.
Assemble rim and backboard to the Backboard Mounting Bracket (A), then attach the Backboard
Mounting Bracket (A) to the end of the pole with 1/2” Square Head Set Screws (M) making sure that the
rim and backboard are level. Fasten Backboard Braces (L) to the backboard with 7/16” x 2” Carriage
Bolts (C), 7/16” Hex Nuts (K), 7/16” Flat Washers (I), 7/16” Lock Washers (J), and to the 3-1/2” Band
Clamps (B) with 5/16” x 2” Carriage Bolts (G), and 5/16” Flange Nuts (H). See Figure 2 and Figure 3
on the following page.
