Instructions
1. Locate and dig a 12" minimum diameter x 36" deep hole.
2. Fill hole with wet premixed concrete, insert vertical pole leaving exactly 108" above desired playing
surface. Vibrate to settle concrete.
3. Check post again, it is important that the top of post be exactly 108" above playing surface. Make sure
post is straight and plumb. Brace while drying if necessary. Allow 24 hours minimum drying time before
continuing assembly. Place 4" square post cap on top of pole.
4. Using 4"x ½" U-Bolts, lockwashers and nuts attach the extension arm support to the vertical pole either
at desired rim height or at ground level. If you choose to use the unit at the 10' playing level, the bottom
of extension arm support D will be located approximately 96" up from playing surface.
5. Loosely attach the lower two extension arms to the extension arm support using a ½"x 10" hex bolt, ½"
locknut and (2) ½" nylon flat washers. (Flat washers fit between extension arm support and extension
arms to prevent paint rubbing) Then, attach the upper two extension arm to the extension arm support
as described above, while doing so make sure to also attach the Insta-Just bracket using the same ½"x
10" hex bolt as shown on Figure A. Figure C indicates which end to attach to Pivot Point H. The Insta-
Just bracket should be installed with the open side facing down.
6. Attach the I-Frame Backboard support to the lower set of arms (I-Frame should be "FACE FORWARD")
using a ½"x 10" hex bolt, locknut and nylon flat washers. ATTENTION: Make sure to also bolt Insta-
Just bracket to Pivot Point G at this time. It fits on the ½" hex bolt located at pivot point G (see figure A)
and straddles the 1" square tubing support at the bottom of the I-Frame. Note: Insta-Just bracket
should be installed with the open side pointing down. Next, attach the upper set of extension arms to
the I-Frame backboard support as described above.
7. Remove and discard the plastic shipping block currently located at the backboard joint. Hang the
backboard on the I-Frame as shown in Figure B. Then, using the 5/16" hardware provided with the
backboard frame, bolt the Backboard I-Frame support to the center four holes located at the top of your
backboard as shown in Figure B. DO NOT TIGHTEN 5/16" HARDWARE AT THIS TIME. Leave the
nuts loose, they will be tightened at the end of the installation.
8. Attach desired rim with the hardware provided in the rim box. Place one rubber gasket (included with
the backboard) between the face of the backboard and
the backplate of the rim, the other should be placed between the Backboard I-Frame support and the
backside of the backboard. Trim gaskets if necessary.
9. Tighten the 5/16" hardware holding the I-Frame Backboard Support to the Aluminum Backboard frame
discussed above in step 7. (see Figure B)
10. Tighten all bolts. Make sure rim is level to board, etc. If you are working at ground level do not tighten
the 4" U-Bolts yet.
11. If the assembly is at ground level: slide entire unit to desire height and tighten U-Bolts making sure
entire project is level and square. IMPORTANT! Over-tightening U-Bolts can cause damage to the
extension arm support, just tighten U-Bolts until they are snug.
