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.
SERIOUS INJURY OR DEATH MAY OCCUR.
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
