Outdoor Basketball Backstop by Draper, call your dealer or

➀Choose the proper location to dig for the concrete footing. When choosing
the exact position to dig, make sure to maximize the amount of playing
surface while minimizing possible driveway obstruction.
➁Dig 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!
➂Assemble the anchor kit as shown in Fig. B (page 2). Thread a
5
/ 8 " hex nut
(L) 2½" of the way onto 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 onto each J-Bolt until tight against the template, making
sure to keep the J-Bolt hooks pointing in toward the center of the tem-
plate.
➃For this step you will need: Level; Broomstick; Tape Measure. The 42" x
24" anchor footing will require approximately ½ 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.
➄Mix 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 Fig. C, page 2).
STOP HERE! Allow footing to cure for seven days before proceeding.
➅Take off the top
5
/ 8 " nuts from the J-Bolts, remove the template and dis-
card it.
➆Thread a second
5
/ 8 " nut on to each J-Bolt down against
the nut embedded in the concrete.
➇Place the vertical post (A) down over the footing making
sure not to damage the J-Bolt threads. Using (4)
5
/ 8 " lock-
washers and the final (4)
5
/ 8 " hex nuts, bolt down post finger
tight with welded tabs facing away from playing surface.
➈Level 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.
➉Attach both pivot stop caps (W) over the ends of the square
blocks (pivot stops) welded near the upper end of the post.
IMPORTANT: FROM THIS POINT FORWARD DURING
ASSEMBLY, BE SURE TO SPREAD A GENEROUS LAYER
OF ANTI-SEIZE LUBRICANT OVER THE ENTIRE SHAFT
OF EACH ½” HEX BOLT. THIS LUBRICANT WILL GUARD
AGAINST RUST, AND HELP ENSURE PROPER PIVOT OP-
ERATION IN YEARS TO COME. NOTICE: Anti-Seize lubricant
is EXTREMELY MESSY. An old toothbrush, etc. may be used
to smear lubricant onto bolts instead of using your finger. Have
clean up rags available.
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). Be sure to smear lubricant on bolt
shaft.
Slide the hole located in the rim height indicator (T) (black plastic with
hole in one end) over one of the second 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 4½" hex bolt (G). Tighten each with a ½"
locknut (J). The rim height indicator should now hang freely along side the
spring-assist cartridge. Be sure to smear lubricant on bolt shaft.
Next attach the hand crank adjustment cylinder (F) using a ½" x 10" hex
bolt (H) and ½" x 4½" hex bolt (G). Tighten each with a ½" locknut (J).
Next, remove and discard the wooden spreader block from the spring-as-
sist cartridge. Be sure to smear lubricant on bolt shaft.

Caution
➀Immediately unpack all components and cross check against bill of
materials.
➁Spring-assist cartridges are shipped under tension. Do not remove
wooden spreader blocks from spring-assists until instructed to do so.
➂Injury may occur if linkages are allowed to fall off main arm during as-
sembly. Be sure to smear lubricant on bolt shaft.
➃Allow concrete footing to cure for seven days before completing
installation. It is advisable to wait up to two weeks to allow the anchor
footing to fully cure before aggressive play.
➄Follow instructions carefully.

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. Be sure to smear lubricant on bolt shaft.
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 "flat-
washer (P), (8)
5
/ 16 "lockwasher (Q), (8)
5
/ 16 "hex nuts ( R ). If your back-
board 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, call
Draper 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 you should 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.
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). Next, attach the
upper H-Frame pivot tube to the upper parallel linkages using (1) ½" x 10"

Check face of backboard to see if it is level forward and back. If it is out of
level, correct it by adjusting the
5
/ 8 "nuts located underneath the vertical
post base plate.
Mount the rim to the H-Frame/Backboard assembly using the hardware
supplied in the rim box. If you purchased an acrylic backboard make sure
to place the second rubber gasket (included with backboard) between the
face of the backboard and the backplate of the rim. Trim gasket if neces-
sary. Use level to make sure rim is level side to side before tightening nuts.
After everything is square, make sure all nuts have been tightened. How-
ever, do not overtighten; if unit is difficult to crank up and down the main
pivot nuts are probably too tight.
To apply the rim height sticker (S), first use a tape measure to crank rim
up to exactly 10' from the playing surface. Use a pencil to make a mark on
the spring-assist outer tube where the rim height indicator stops. Then,
peel and apply sticker to outside of spring-assist cartridge lining up the
pencil mark with the 10' mark on the sticker. See Figure A (below) for a
diagram of a completed height indicator assembly.
Note: It is advisable to wait up to two weeks to allow the anchor footing to fully
cure before aggressive play.
