1. Position the Vertical Pole (A) taking into consideration that the BA47 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.
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” Dia. 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 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 BA47 Backboard (I) over the top lip on the Extension Arm (B) and attach the BA47
Backboard (I) to arm with the 7/16” hardware provided (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
