1. Call your local utility locating service, usually by dialing 811, before digging to avoid serious injury or

service interruption.

2. Select the location for the concrete base footing. Note that the face of the Backboard (Q) will be

approximately 48” from the center of the footing for a BA777 Pole and 60” for a BA777XL Pole. Dig

a 12” diameter hole that is 48” deep. Remove additional soil from the bottom 1/3-1/2 of the hole in a

bell shape to add pole stability. In areas where the normal frost line is below 48” it is advisable to dig

to the normal frost line. See Figure 1.

3. Make sure that you have a level and a broomstick or similar pole to vibrate air pockets out of concrete.

A 12” diameter by 36” deep hole with a bell bottom will require approximately 4 cubic ft. or 3000 PSI

Quick Dry Concrete (T). You will need to adjust the amount depending on the size of hole you

prepared. Having too much is better than having too little.

4. 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.

9. Install the Backboard Mounting Bracket

(B), Backboard (Q), and Rim (R)

assembly onto the end of the Gooseneck

Pole (A). It is easiest to install the

assembly upside down and then rotate

180° before installing and tensioning the

1/2” Square Head Set Screws (O).

Confirm that the Rim (R) and Backboard

(Q) are level before tightening the 1/2”

Square Head Set Screws (O) against the

Gooseneck Pole (A). Install and tighten

the 1/2” Jam Nuts (P) to lock the 1/2”

Square Head Set Screws (O) in place. See

Figure 4

Figure 2

5. Attach one Band Clamp (C) with 5/16” x 2”

Carriage Bolt (H), and 5/16” Flange Nut (I)

approximately 12” from the bottom end of

pole and insert pole into concrete while

vibrating concrete to allow it to surround the

pole completely. The horizontal extension

section of the pole should be parallel to the

playing surface, perpendicular to the

intended court end line and the lower

surface of the horizontal portion of the tube

should be 9’ 6 1/2” above the playing

surface. You will need to brace the pole to

maintain this dimension to insure the rim

height will be at official 10’.

See Figure 1 & 2

6. Trowel the top of the concrete smooth and

clean any excess off the Gooseneck Pole

(A). Allow the footing to cure for at least

48 hours. Do not proceed any further until

concrete is completely cured.

8. Slide two Band Clamps (C) onto the

horizontal portion of the Gooseneck Pole

(A). See Figure 4.

7. Attach the Rim (R) and Backboard (Q) to

the Backboard Mounting Bracket (B) using

the hardware provided with the Rim (R).

See Figure 3.

10. Referencing the illustrations below fasten Backboard Braces (N) to the Backboard (Q). Each model will

require different hardware to attach the Backboard Braces (N) to the Backboard (Q). BA475SS &

BA407G/U require 3/8” x 1” Hex Bolts (E), 3/8” Flat Washers (F), and 3/8” Lock Washers (G).

BA495 & BA47 require 7/16” x 2” Carriage Bolts (D), 7/16” Flat Washers (K), 7/16” Lock Washers (L),

and 7/16” Hex Nuts (M). Backboard Braces (N) will need to be bent on the ends to match the angles of the

Backboard (Q) and Band Clamps (C). Exact angle will depend on the Backboard (Q) model selected. This

can easily be accomplished in a number of ways, including contacting the end of the Backboard Brace (N)

on a concrete surface. See illustrations below.

12. Confirm Backboard (Q) and Rim (R) are still level before drilling a 1/4”

diameter hole into the Gooseneck Pole (A) using the pilot hole in the

Backboard Mounting Bracket (B) as a guide. Install the 1/4” X 1” Roll

Pin (S) into the hole you just drilled with a hammer to further reduce the

risk of rotation or movement. See Figure 7

13. Attach Net (R) and optional Pole Pad (U) if applicable. The system is

now ready for play.

11. Attach the other ends of the Backboard Braces (N) to the Band Clamps (C)

using the 5/16” x 2” Carriage Bolts (H) and 5/16” Flange Nuts (J). See

Figure 6.
