Instructions
1. Choose the proper location to dig for the concrete footing. Use the distance chart in figure A to help you make your decision. When
choosing the exact position to dig, make sure to maximize the amount of playing surface while minimizing possible driveway
obstruction.
2. Dig hole 42" deep and 24" square. Be sure to bell out the bottom 12" of the hole to give added stability to the footing. NOTE: If you
live in an area where the frost line is below 42" it is advisable to dig to normal frost line. Do not cheat on the hole size, it is imperative
that the hole be a minimum of 42" deep and 24" square!
3. Assemble the anchor kit as shown in figure B. First thread a 5/8" hex nut (L) 2 ½" of the way on to each J-Bolt (K). Place the
threaded end of each J-Bolt through the 4 holes located in the anchor template (M). Then thread a second 5/8" nut on to each J-Bolt
until tight against the template, making sure to keep the J-Bolt hooks pointing in toward the center of the template.
4. For this step you will need: Level; Broomstick; Tape Measure. The 42" x 24" anchor footing will require approximately 1/2 yard of
3000 psi concrete (30-32 60# sacks of premix concrete). More will be needed if you dig a larger hole. Make certain that you have
enough concrete to finish the job. Allowing a portion to dry while you purchase more concrete will weaken the footing.
5. Mix the concrete according to the instructions on the bag. It is better to mix it slightly wet than too dry. Fill the hole full to ground level
with as little time between batches as possible. Insert the broomstick in 3 or 4 different places and vibrate up and down to settle the
concrete. Submerge the (4) anchor footing rebar pieces (N) into the center of the hole spaced evenly. Next set the anchor bolt
assembly into the wet concrete, vibrate it as it goes in to make sure the concrete fills in around the J-Bolt hooks. Make sure the
template is pressed firmly against the top of the wet concrete. Use the level to ensure that it is level in all directions. Additionally, the
center line of the J-Bolts must be parallel with the edge of the playing surface. (See figure C)
STOP HERE! Allow footing to cure for seven days before proceeding.
6. Take off the top 5/8" nuts fromthe J-Bolts, remove the template and discard it.
7. Thread a second 5/8" nut on to each J-Bolt down against the nut embedded in the concrete.
8. Place the vertical post (A) down over the footing making sure not to damage the J-Bolt threads. Using the final (4) 5/8" hex nuts, bolt
down post finger tight with welded tabs facing away from playing surface.
9. Level the vertical post by adjusting the 5/8" nuts located underneath the base plate. Then tighten top nuts against the top side of the
base plate.
10. Slide the main arm (B) over the top of the vertical post and attach to the lower pivot tube with a ½" x 10" hex bolt (H) and ½" locknut
(J).
11. Slide the hole located in the rim height indicator (T) (black plastic with hole in one end) over one of thesecond set of welded tubes
in the main arm. Attach the spring-assist cartridge (E) to the second set of attachment holes on both the main arm and the vertical post
welded tabs utilizing a ½" x 10" hex bolt (H) and a ½" x 4 ½" hex bolt (G). Tighten each with a ½" locknut (J). The rim height indicator
should now hang freely along side the spring-assist cartridge.
12. Next attach the hand crank adjustment cylinder (F) using a ½" x 10" hex bolt (H) and ½" x 4 ½" hex bolt (G). Tighten each with a ½"
locknut (J). Next, remove and discard the cardboard spreader tube from the spring-assist cartridge.
13. Attach parallel linkages ( C ) to vertical post with ½" x 10" hex bolt (H) and ½" locknut (J). Attention: It does not matter which end of
the parallel link you attach to the vertical post.
Caution: Injury may occur if linkages are allowed to fall off main arm during assembly.
14. Next, assemble the H-Frame backboard mounting (D) to the backboard as shown in figure D. Use the (8) 5/16" x 1" machine
screws (O), (8) 5/16" flatwasher (P), (8) 5/16" lock washer (Q), (8) 5/16" hex nuts ( R ). If your backboard is tempered glass check to
make sure all four steel grommets are located at the rim holes, if any are missing check in the box. If grommets are missing and cannot
be located, DO NOT proceed with assembly, callHoops immediately. If your backboard is acrylic you must remove and discard the
plastic shipping block from the backboard joint to complete this step. Additionally, if you purchased an acrylic backboard youshould
have received two rubber gaskets enclosed with the backboard. Place one gasket between the H-Frame backboard mount and the
backside of the backboard. You will use the other gasket later during assembly. Rubber gaskets are necessary for acrylic boards only.
15. Mount the H-Frame/Backboard assembly lower pivot tube first to the main arm using (1) ½" x 11" hex bolt (I) and (1) ½" locknut (J).
