1. Position the Vertical Pole (A) taking into consideration that the BA47U/BA47A Backboard (I) will be
approximately 5' from the front of the Vertical Pole (A). Dig a 12" minimum diameter by 48" deep
hole. It is advisable to bell out the bottom of the hole about 4" larger in diameter. A larger diameter hole
is always better than a hole that is not large enough. If you are installing in loose, sandy or otherwise
non compacted soil increase hole diameter to at least 24". Never install using Sonotubes. Pole must be
installed in the center of the concrete footings to avoid footing failure.
2. Make sure that you have the following tools available prior to pouring the concrete footing: a level, a
broomstick or similar pole, bracing materials, and a tape measure. If you have made your hole larger
than 12" diameter x 48" deep, than you will require more concrete. Having enough concrete before you
start will ensure proper strength of the footing.
3. Mix concrete according to instructions on the bag. It is advantageous to have the mixture be "wet".
This will increase your working time and allow the batches to mix in the hole. Pour the hole full to
ground level. Insert the broomstick into the wet concrete and agitate up and down, REPEAT
SEVERAL TIMES. Insert the Vertical Pole (A) into the concrete while continuing to agitate broomstick
to ensure the mixture fills in good around the Vertical Pole (A). Make sure that at least 100" of pole
extends above desired playing surface to ensure official 10'-0" playing height. (Approximately to decal
on pole, see illustration.) Clean excess concrete off of the Vertical Pole (A) with a damp towel and
smooth the top of the footing. Level the Vertical Pole (A) and apply bracing materials to support while
concrete cures.
4. Install 4 (four) Spring Pins (H) in Mounting Plate (C) so that they are flush with the back side of the
Mounting Plate (C). Install 4 (four) Spring Pins (H) in the Mounting Plate (C) on the Extension Arm
(B) with the Spring Pins (H) flush to the BA47U/BA47A Backboard (I) side. These Spring Pins (H) are
essential to the alignment of the Extension Arm (B) to the Vertical Pole (A). Spring pins will be pre-
installed in "Hot-Dip" Galvanized poles.
5. After allowing 48 hours curing time for the concrete, mount the Extension Arm (B) as shown using
hardware provided. The Extension Arm (B) can be loosely mounted at the ground level and raised to
correct height depending on equipment availability.
WARNING! EXTENSION ARM IS EXTREMELY HEAVY! STAY AWAY FROM THE AREA
BELOW THE EXTENSION ARM/BACKBOARD WHILE INSTALLING OR ADJUSTING.
6. Install the Model BA47U/BA47A Backboard (I) over the top lip on the Extension Arm (B) and attach the
BA47U/BA47A Backboard (I) to arm with the 7/16" hardware provided (L)(M)(N)(O). Finger tighten
only.
7. Install the Model BA39U Rim (J) using the hardware provided with it.
8. Tighten all bolts making sure the Model BA39U Rim (J) is at the desired height.
9. Install the Pole Cap (P).
10. To eliminate possible loosening of the extension arm bolts by vandals, which could cause serious injury
or death, distort the thread on the six 5/8" x 8" Hex Bolts (D) with a chisel and hammer
SERIOUS INJURY OR DEATH MAY OCCUR.
