Your RetroFit42 H-Frame Backboard Support is designed to allow most
First Team (42” tall) backboards to be hung on virtually any existing
basketball post having a minimum 6”x6” mounting plate at the end of
the post’s extension arm.
1.
Unpack and lay backboard face down on flat surface.
2.
Next, assemble the H-Frame backboard mounting to the backboard
as shown in Figure A. Use the (8) 3/8” x 1 ¼” hex bolts,
flatwashers, lockwashers and hex nuts. Insert the hex bolts with
the heads of the bolts on the OUTSIDE of the backboard frame.
Use the flatwashers, lockwashers and hex nuts to fasten the bolts.
If your backboard is
tempered glass or acrylic
, 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 First Team
immediately. (NOTE: If your backboard is clear acrylic, you will
not use the 2 rubber gaskets included in the backboard box)
3.
Next, check the plate attached to the end of the extension arm on
your basketball post. The plate must have four 7/16” diameter
holes spaced exactly 5” apart horizontally and at least 5” apart
vertically. If your mounting plate does not, you will need to drill
holes in your plate before proceeding. (see Figure B)
4.
Insert (1) 3/8”x1 ½” carriage bolt into each of the four mounting
holes in the plate at the end of your existing extension arm. Insert
the bolts so the round heads on the carriage bolts are facing the
basketball court. Loosely secure with (1) 3/8” flatwasher,
lockwasher and hex nut on the back side of the mounting plate.
5.
The RetroFit42 backboard mount has two vertical attachment slots
with large round openings at the top of the slot (see Figure A).
These large round openings are designed to allow the heads of the
carriage bolts to slide into the slots. Raise the H-Frame/Backboard
assembly into position allowing all four carriage bolts to engage the
vertical slots on the H-Frame. Raise H-Frame/Backboard assembly
until the top rim bolt holes in the backboard are approximately 9’
11” above the playing surface. Tighten all four 3/8” hex nuts.
6.
Mount the rim to the Backboard/H-Frame 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 necessary. Use a level to
make sure rim is level side to side relative to backboard before
