Portable Basketball System
1. VERTICAL UPRIGHTS AND EXTENSION
BOOM - Two vertical uprights constructed of heavy gauge
2"x 5" rectangular tubing shall support the main
extension boom. Both vertical uprights shall each be supported
by two 2"x 2" square tubular braces. The main
extension boom shall be constructed of heavy gauge 4"x
4" square tubing with a 3"x 3" inner telescoping
"slide boom." Backboard to base extension shall
be 66" with rim at 10' playing height and a minimum
of 48" at lower playing heights. Units without adjustable
"slide-boom" extension are not considered equal.
Extension boom design shall provide for the direct rim mounting
of the rim to the main extension eliminating backboard stress
when rim is contacted. Two tubular braces shall further
support the upper corners of the backboard.
2. BASE CONSTRUCTION - The
base is all steel construction comprised primarily of 3"
x 1 ½" rectangular steel tubing. The front of
the base shall measure 48" across for maximum stability
during play. The ballast box (ballast not included) shall
be designed to accept (24) 4"x 8"x 16" solid
cement blocks each weighing 30 lbs. (720 lbs. total). The
unit shall ride on four large 8" non-marking wheels
for easy "one person" portability. Units using
less than 8" wheels are difficult to move and are not
considered equal. The front two wheels shall be on self
locking castors (swivel lock & roll lock) which may
be easily engaged once unit is positioned for play.
3. SPRING ASSISTED FOLDING,
SETUP AND ADJUSTMENT - The unit shall operate via "Spring-Assist".
Four 3 ½" painted coil springs support the weight
of the backboard, rim, extension boom, padding and uprights
(NO HYDRAULICS). Coil springs shall be painted to match
the color of base. Plated springs are not considered equal
due to "hydrogen embrittlement" which takes place
during the plating process. Rim height shall be adjustable
in six-inch increments from regulation 10' height down to
6'via a removable adjustment pin. The Spring-Assist system
is operated easily by one person.
4. PIVOT POINTS - All pivot
point locations rotate on high load, maintenance free bushings.
5. BASE, UPRIGHT AND BALLAST
BOX PADDING - Unit shall be equipped with standard 2"
thick foam padding mounted on 7/16" wafer board covered
with a 14 oz reinforced vinyl laminate. Side pads and ballast
box pad use 1 ½" thick foam as standard. Padding
shall be secured to unit via 2" velcro attachment straps.
Padding need not be removed during folding adjustment, transportation
or storage. Colors are available.
6. FINISH - Entire unit shall
be covered with a black powdercoat finish.
7. BACKBOARD - Constructed
of 1/2" thick acrylic with bright white screening.
The framework shall be constructed from clear anodized aluminum
"L" type extrusions. Overall backboard size shall
be approximately 60" wide and 36" high.
8. RIM - Flexible type so
as to absorb the stress of player contact. The rim shall
be of institutional quality with an official 5/8" diameter
ring. Ring opening diameter shall be the standard 18"
I.D. Rim shall have an orange powder coated finish. Heavy-duty
nylon net shall be provided. Entire system shall be durably
designed and constructed to allow for "dunking"
action without compromising structural integrity or stability.
9. WARRANTY - Complete unit
carries a Lifetime Limited Warranty. Entire system weight
shall be approximately 1165#
