4. A 20” diameter by 48” deep hole will require approximately 1/2 cubic yard of 3000 psi concrete (22-24
60# sacks of premix concrete). Allow for more if the hole is deeper or wider. Make sure you have enough
concrete before pouring, because allowing a portion to dry before the hole is completely filled will affect
the strength of the footing.
5. You are now ready to complete the most critical portion of the installation. Please note (and avoid) these
COMMON INSTALLATION PROBLEMS:
♦ Proceeded without reading instructions fully.
♦ Stopping short of the required hole size.
♦ Underestimated amount of concrete required, part of base/footing dried before you could finish
pouring.
♦ Just “eyeballed” the squareness of the base, when assembled, the pole and board are not parallel or
square to your driveway/playing surface.
♦ Didn’t allow enough time to correctly complete the project. Setting this base properly ensures the
function and appearance of your system.
♦ Being overanxious to mount the pole and board before the footing was fully cured. (A defective footing
is harder to dig out than to install.)
♦ Damaged threads on J-Bolts making it impossible to install nut.
6. Drive 36” Rebar (B) into the bottom of the hole. Equally space the rebar so that it forms a square.
7. Mix the concrete according to the instructions on the bag. It is a good idea to have the concrete mixture be
“wet”. This will increase your working time and allow batches to mix in the hole. Pour the hole full to
ground level. Insert the broomstick into the wet concrete and agitate it up and down. REPEAT SEVERAL
TIMES.
8. Insert the “J” bolt assembly Template (C) and “J” Bolts (A) into the wet concrete. Be sure the bolt pattern
is parallel with the desired position of the backboard and the edge of the playing surface. Use the tape
measure to double check. Vibrate the assembly as you insert it so the concrete fills in around the “J” Bolts
(A). Be sure the Template (C) is pressed firmly against the surface of the wet concrete. The top of the
concrete footing must be flush with the playing surface.
9. Clean excess concrete from edge of hole and level the concrete from the edge of the Template (C) to the
edge of the hole. Check the level of the “J” Bolts (A) again.
10. ALLOW FOOTING TO DRY FOR SEVEN (7) DAYS. ONLY AFTER CONCRETE HAS CURED FOR
SEVEN DAYS SHOULD YOU PROCEED.
11. Once the concrete is cured you may now remove the upper 5/8” Hex Nuts (D) from the “J” Bolts (A) and
remove and discard the Template (C).
12. Place the 5/8” Hex Nuts (D) you just removed back on each “J” Bolt (A) and finger tighten against the nut
that is embedded in the concrete footing. Install one 5/8” Flat Washer (F) on top of each 5/8” Hex Nut (D).
See Figure B.
13. Install the base of pole over the “J” Bolts (A). Place 5/8” Flat Washers (F), 5/8” Lock Washers (E) and
5/8” Hex Nuts (D) on “J” Bolts (A) to tighten base down. You can level pole if needed by adjusting the
5/8” Hex Nuts (D) above and below the base plate. Make sure all hardware is tight once leveled. Press
Safety Cap (G) over the exposed ends of “J” Bolts (A). You are now ready to finish the installation of your
basketball system. See Figure B.
