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.
