1. Call your local utility locator 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 (P) will be distanced
from the center of the footing according to information in Figure 12. 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 48” deep hole with a bell bottom will require approximately 5 cubic ft. of
Quick Dry Concrete (S). 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.

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” (except PR78, which should measure
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 13.
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.
7a. On systems PR74, PR78, PR79, PR79XL, PR87 and PR87XL, assemble Backboard Conversion Plate (U),
Backboard Mounting Adapter (B), Backboard (P) and the Rim (Q) using the hardware provided with the
Backboard Conversion Plate (U). See Figure 2.
7b. On systems PR75, PR75XL, PR76, PR77, and PR77XL, assemble Rim (Q), Backboard (P) and
Backboard Mounting Adapter (B) using the hardware provided with the Rim (Q). See Figure 3.
7c. On Systems PR87, PR87XL assemble Backboard
Conversion Plate (U), Backboard Mounting Adapter (B),
Backboard (P) and two Backboard Spacer Plate (V)
using the hardware provided with the hardware provided
with the Backboard Conversion Plate (U). See Figure 4.
8. Slide two Band Clamps (C) onto the horizontal portion
of the Gooseneck Pole (A). See Figure 5.

9. Place the assembly from 7a or 7b or 7c above on to the
end of the pole. It is easiest to place the assembly onto the
end of the pole upside down and then rotate 180° before
installing and tensioning the 1/2” Square Head Set
Screws (N). Confirm that the Rim (Q) and Backboard (P)
are level. Tighten the 1/2” Square Head Set Screws (N)
against the Gooseneck Pole (A), then tighten the 1/2”
Jam Nuts (O) to lock the 1/2” Square Head Set Screw (N)
See Figure 6 and Figure 7.
10. The Backboard Braces (M) will get attached to the Band Clamps (C) on one end, and the Backboard (P)
on the other end. The tabs on the end of the Backboard Braces (M) will need to be bent to match the angles
necessary to mount the Backboard Braces (M) to the Backboard (P) and Band Clamp (C) depending on the
Backboard (P) that is part of your system. This can easily be accomplished in a number of ways including
contacting each end on a concrete surface.
11. Attach the one end of each Backboard Brace (M) to one of the two Band Clamps (C) using
5/16” Carriage Bolts (H) and 5/16” Flange Nuts (I). See Figure 8.

12a. If you are installing PR75 or PR75XL system with a
BA475SS Backboard, use 3/8” x 1” Hex Bolts (E),
3/8” Flat Washers (F), and 3/8” Lock Washers (G) to
attach the other end of the Backboard Braces (M) to
the threaded holes in the rear of the Backboard (P).
See Figure 9.
12b. If you are installing a PR74, PR78, PR79, or
PR79XL with a BA42UC, BA407U, or BA472PC
Backboard (P) use 3/8” x 1” Hex Bolts (E),
3/8” Flat Washer (F), and 3/8” Lock Washer (G) to
attach the other end of the Backboard Brace (M) to
the threaded holes in the rear of the Backboard (P).
See Figure 10.
12c. If you are installing a PR76, PR77, PR77XL,PR87,
or PR87XL, with BA495, BA47 or BA472
Backboard (P) use 7/16” x 2” Carriage Bolts (D),
7/16” Hex Nuts (L), 7/16” Flat washers (J), and
7/16” Lock Washers (K) to attach the other end of
the Backboard Braces (M) to the Backboard (P).
See Figure 11.

13. When Backboard (P) and Rim (Q) are level, drill 1/4” diameter hole into Gooseneck Pole (A) using the
pilot hole into the Backboard Mounting Adaptor (B) as guide. Insert 1/4” x 1” Roll Pin (R) with a hammer
to reduce risk of rotation or movement. See Figure12.
14. Attach Net (Q) and Optional Pole Pad (T) or Backboard padding if applicable.
15. System is ready for play.
