Footing:
NOTE: Before digging, call to locate any buried utility lines.
a.
Dig a hole 48" deep x 36" across. The edge of the hole should be flush with the edge of
the playing surface. If you live in an area where heavy frost can occur, it may pose a
problem, consult your local building inspector to determine the appropriate hole depth.
NOTE: The hole must be at least 48
"
deep.
b.
There must be at least 3 feet of clearance behind the unit to enable the user to adjust the
height.
c.
Mix the concrete according to the instructions on the bags. Note that a thicker mix of
concrete will dry stronger than a thin mix. Pour the concrete into the hole, stopping
approximately 18 inches from the top of the hole.
d.
Assemble the ground anchor kit as shown below.
e.
Insert the four pieces of 1/2” x 36” rebar into the hole, pushing each piece firmly to the
bottom of the hole. The four pieces should be arranged in a square approximately 8 - 9
inches wide so that each piece of rebar will be positioned surrounding the backstop post.
f.
Finish filling the hole to the top with concrete. And insert the ground anchor kit on top of
the concrete.
g.
Allow the concrete to cure a minimum of 72 hours before proceeding. In humid climates
or wet weather, allow additional time for the concert to cure.
Ground Anchor Kit:
Thread a M16 Hex Nut onto each of the J-Bolts. Securely tighten the Nuts all
the way down to the end of the threads. Slide the threaded ends of the J-Bots
through the holes in the corners of the J-Bolt Template and secure them with
M16 Hex Nuts as shown. Securely tighten all Nuts at this time.
NOTE: Make sure the curved “J” ends of the J-Bolts are oriented in a rectangular
pattern as shown.
